Removing clear coat with ultimate compound?

[MicrofiberMan]

I was wondering how many times you would have to use ultimate compound before you removed to much clear coat, lets say you were using a meguiars dual action with a meguiars cutting pad, roughly how many times would you have to use it figure you're doing 5 passes at a time

As far as compounds go, Ult Compound is fairly mild. You would be hard pressed to do any serious paint (clear coat) removal during the course of a normal compounding with UC.

Oh really, thanks for the quik reply, what would you have to use to remove to much clearcoat something like ultra cut 105?

Even with the da on high with a cutting pad?

IMO, assuming the paint is sufficiently hard, you can compound with UC/M105 on foam hundreds of separate times with many dozens of passes each - even that might be a low figure, because those are medium-strength combos that are not actually cutting the clear without a lot of work. However, if the paint is sufficiently soft, it might only take a handful of corrections before the clear is compromised. Of course, in that case, you wouldn't be using UC/M105 regularly in the first place, but UP/M205 instead. Changing the variables, say using a Rupes instead of a Porter Cable, or a Porter Cable instead of a DA Power System, MF instead of foam, or M101 instead of UC/M105, would change the outcome. So, it all depends. You have to get a feel for how your paint is responding when you're correcting scratches and other defects.

Thanks Top Gear--this is something I had been wondering about as well. Since my car is 'new' (delivered 3/2016, manufactured 9/2015), I was a bit reluctant to use UC again in short order ( did a full UC correction about 6 weeks ago using UC on foam with a HF DA, heavy pressure on highest speed).

As you pointed out it really depends on the hardness of the paint. My paint is super hard, and I still have swirl marks to remove (funny how they are so easy to put in the finish but so hard to remove).

Once the new paint from the body shop cures (different thread), I will tackle them again.

If you stay within Meguiar's Consumer Line of products they are all pretty mild in comparison to the Professional Line products. Basically you would have to do something incredibly stupid to burn through your paint with a Porter Cable ... something like using a compound at high speed with a cutting pad or mf pad with pressure on an edge, or swing the PC around by it's cord and slam it down on the hood.

Meg's UC and UP are very user friendly & like mentioned on the mild side. I would rather be too mild and have it take several passes (or sessions) to clear up a paint job than risk going too aggressive and damaging the paint. I use a cutting pad on my black Camaro all the time (usually with UP) and it has never cut too much or even left hazing.

Just use common sense and you'll be fine.

Re: Removing clear coat with ultimate compound?

I've achieved strike through with Ultimate Compound, a Porter Cable 7424xp, and a Green Hex Logic pad. All the years using a rotary, with Meguiar's wool and foam pads - no problems. First time with a PC.. That happened.. I've even removed 1000 grit sanding marks with it on a moderately soft single stage. Speed 6, light pressure. Foam pads.

Not that you will experience that, but that was mine. I love that combo, and it's actually my go to for serious heavy cutting.

Re: Removing clear coat with ultimate compound?

Did my car again yesterday, i wet sanded a few scratches with 3000 grit, used ultimate compound on a few panels, then mirror glaze finishing polish first with a polishing pad then again with a finishing pad, its as good and polished as i can possibly get it, a few small scratches are still there that i didn't want to wet sand but im not going to polish again for a year and it will be light, I cant get it any better then it is with the tools and knowledge i have right now.
