Well, decided to try out the rotary polisher for the first time yesterday evening... Wasn't sure what to expect from it, wondering if it would be this fire breathing monster that was going to burn the paint as soon as look at it!! :lol: :lol: So, I watched the Machine Polishing DVD by Brazo, focussing down on the rotary technique side of things.

Then out with the door - this first practice is divided into three parts:

Part 1 - Basic Swirl Removal
For a first attempt, I deicded to have a look at removing basic light swilrs from my scrap door...

I decided to taclke this with Menzerna Final Finish (cerami-clear) using a Megs Yellow W8006 pad by the Makita. The aim was to see what swirls I could shift with a light polish and pad, and to see what finish I could get without cracking out the PC. So, applied the product to the pad, then swithced on at 600rpm and primed the pad up with small movements of the Makita. Then spread around the area at 600rpm. Up then to 1000rpm for a two or three passes before moving to 1200rpm to polish until the FF started to go clear. Buffed off residue with a mf towel, and here's the results: ~5um of paint removed.

Half and half...

Full after...

The light swirls had gone with ease, very quickly, and I was pleased with the finish achieved - no visible holograms that I could pick out reflecting away in the sunlight... So I was pretty happy with that. But... well, that wasn't really much of a challenge now, was it?! :lol: Lets try some proper swirls...!!


Part 2 - Steel Wool Test A
Some careless soul then decided it would be a good idea to try and remove some of the welded on gunk from the bodyshop with steel wool... :rolleyes: Wonder who that could have been?!! ;) :lol: Anyway, the steel wool couldn't shift the wee spots on the panel (finger nail did) so excuse them in the following photographs, I'll get back to them!

Anyway, here's some swirls from the steel wool treatment:

And the damage highlighted under the Brinkmann Dual Xenon:

To remove this damage, I decided to go with Menzerna Intensive Polish (RD3.01, cerami-clear). Applied using a Meguiars Yellow W8006 pad. This door is off a Peugeot 307, so I suspected soft paint. Anyway, first hit with the IP - primed at 600rpm, spread at 600rpm, the polished at 1000rpm for a couple of passes then up to 1200 then 1500rpm to polish with only light pressure until it went clear. This made a big dent in the swilrs, but deeper ones remained so this was repeated. The results I though were pretty good after this, just finished off with Final Finish applied as above in Part 1, and he're the finished article (PC was not used at any point, the finish is purely from the rotary):

and a 1/2 and 1/2 shot...

And now, in only fairly dim light the finished result showing much more gloss and the damage of the steel wool still clear to see in even dim light:

A half and half shot in bright sunlight...

And now - a before, half and half, and after shot using the sunlight to highlight the severity of the swilrs inflicted (useful with a panel, you can tilt it to the desired angle!! :) )

I was pretty pleased with the finished article and the results achieved from rotary alone - personally, I wouldn't bother getting the PC out to finish that panel, I though the finish was good from the rotary... but this is my first effort, so guys, comments are needed here on whether you'd have finished down with the PC.


Part 3 - Steel Wool Test B
Now, I wanted to try out a more aggressive Meguiars W7006 Burgandy pad and Menzerna Power Gloss, so some deep swilrs were needed!! :lol:

Bryan had joined me to test out his new rotary as well (an Aote), so he inflicted some nice deep swirls in the lower half of the door with steel wool:

http://img62.imageshack.us/img62/3228/part3abefore8nj.jpg (http://imageshack.us)

We masked off the door into half and hlaf, and Bryan tackled one side and I did the other... I'll let Bryan tell you how he got on with his side of the door, using an Aote rotary with Autoglym and then Meguiars pads...

On my half of the door, I went straight for Power Gloss using the W7006 Burgandy pad. Good spray of Last Touch on the pad, the apply the product. Pad was primed at 600rpm, then PG was spread. Then I went straight to 1200rpm with no pressure and made a few passes, then added a wee bit of pressure and up to 1500rpm for more passes until the PG started to go clear. Stopped, sprayed the pad with Last Touch and repeated some more passes at 1200, then 1500rpm. Then stopped when it went clear again, and buffed off the residue. The result after one hit of PG:

http://img62.imageshack.us/img62/7468/part3b1pg3id.jpg (http://imageshack.us)

Big improvement, but some deeper scratches remained, so the above process was repeated - after two hits of PG:

http://img152.imageshack.us/img152/3523/part3c2pg9uz.jpg (http://imageshack.us)

Nearly there, only the very deep ones remained... I suppose I could have finished the panel at this point, but I wanted to give it some abuse :devil: So, a third pass, this time with added pressure and for fun knocked the speed up to 2000rpm (no I wouldn't do this for real on a car, was just playing herre!! :lol: ). The result - well the scratces had pretty much gone, the panel got hot (was radiating heat) and for the first time I saw holograms clearly uner the Brinkmann light:

http://img93.imageshack.us/img93/1044/part3d3pg2rc.jpg (http://imageshack.us)

Ooops! :lol: But no paint burning, and the holograms were easily fixed - a little bit of Final Finish:

http://img98.imageshack.us/img98/5076/part3eff4dn.jpg (http://imageshack.us)

Bingo! :) Happy with that!

Here's a half and half pic...

http://img98.imageshack.us/img98/5068/part3dave5zc.jpg (http://imageshack.us)

All in all, I am pretty pleased with my first ever effort on the rotary... I'll improve with practice, there's plenty of paint left on that door and when it runs out, I'll just get another and practice spraying on this door! :lol: More practice, then I'll start to be willing to crack the tool out on a car for real.

A couple of things I noticed: with the Power Gloss, I got far less micromarring with the Makita than I did with the PC, Makita breaking it all down more effectively? PG was definitely easier to use on the rotary I found. Also, I actually found control of the rotary to be easier than the PC - no vibration, and the device glides far more and doesn't kick or tug at all. It feels a very flowing tool to use.

Also had a shot of Bryan's Aote using the Autoglym pads, and I found this more difficult going. The Megs pads, IMO, knocked spots of the Autoglym ones as far as defct removal goes... Also found the Aote speed varied, even under no applied pressure which made it dmore difficult to predict and use. The Makita held a constant speed, and flowed much better as a result. Just my thoughts anyways. Bry tried out the Makita as well as the Aote so I'm sure he can comment on the differences he found too.

Next up, I will try out the Megs #80 and #80 combo by rotary and see what I get. The menzerna polishes seemed very easy to use. Watch this space! :thumb:

80 on a rotary is my go to product...

However, you did an amazing job on that panel, awesome!!! Its fun, isn't it...

Sometimes I get upset when a customer has good paint and I don't have to use a rotary...

This tread did it :bigups I am buying that cheap rotary I saw the other day :) I know in theory how to use it and I'll just start with the lowest setting and #80 and a finnishing pad, beeing sure not to put any pressure and keep it moving all the time. I now have a Cyclo and it's ok, but takes too much time to remove any swirls with it.

Great writeup. Very informative. Everyone should get an old scrap body part and practice like you did. I know Megs recommends this also, especially with a rotary. Not so much with the DA, because you can't really hurt things with that.
Thanks for taking the time and effort to make this posting.:xyxthumbs

Thanks for doing such a great write up. I find this very educating and inspiring. I have a cheap Makita knock off I bought off of ebay for $50 just to play around with about a month ago, but havent used it yet. Your thread has inspired me to get a test panel and play around with it.

Thanks,
matt

Well done :bow :bow
thats the best thing to do is to play around with a test panel b4 you hit the big time lol

Looks like you picked up rotary skills very quickly! The pictures show what can be done with a rotary. Nice job!

I don't know anything about the Menzerna polishes. Are they meant for rotary use only?

Menzerna is an excellent company. Their polishes can be used with a dual-action polisher such as the G100.

Nice Post!!
I just got a rotary this weekend. Went straight to the hood of my 95 Ford Windstar, with 80 and a 9006 pad. Like you I started very slow & careful. I was amazed at the kind of job it did even at the slow speeds. I was pleased with the results that I got with it. My hood was already in good shape, so not a good test. Didn't want to do the steel wool trick to it. LOL. I plan on trying it out on a junk repo that a friend has. Just to see what the limits are on some different more aggressive products & pads. It never hurts to practice.
Later the Fox!

When I first read this post, I did not have a Makita - now I do, rarely go to the PC anymore. I also discovered that you can use the rotary just to polish the paint and get it ready for the last step. I use Lake Country pads so it's the white one - I'm sure there is an equal one from Meg's - that and some light polish on 1000-1200 rpm and the paint looks great. Just finished a Surburban and a Buick, both had no swirls (caused they never get washed!) after a good cleaning, the Makita brought the paint right back to showroom shine. Now, both machines -PC and rotary have there place, it's easier to use a PC on doors and fenders till you get the hang of the rotary. And the PC is safer, but it sure vibrates your hands and the noise!
