what is causing residue to occur? M105 with W8000 pad

[WhiteLX]

1989 Mercedes 560 sec. original paint

I am using a Makita rotary on level 3 (1500rpm) with an 8" W8000 pad. Outside temperature is approximately 64 degrees. I am in the sun, but the body is cool to the touch. This occurs after approximately 15 seconds of buff time. The only way to get it off is to soak the area in M34 and wipe down firmly with a microfiber. A light mist of M34 and more buffing does nothing.

The car has not been buffer or waxed in years. It been sitting outside and the paint is in terrible condition, possibly very dried out. It does have some clearcoat failure on the top surfaces. I used M80 on a W8000 pad as well, but resulted in the same difficult to remove residue being left behind.

Too much product?

could have been. Although I wasn't using all that much. I ended up switching to a wool pad with the 105 and it worked much better. Only got a fender and hood completed this afternoon, so I still have a lot more to do. Not sure if I'll follow up with M205 or M80.

Looks like you over worked the product to the point that it dried out on you.

This was occurring just after spreading the product. I was able to work it far longer than 15 seconds on the wool.

M105 can dry up fast on older and/or neglected surfaces. M80 would usually be my recommendation then follow with M105, but if that's doing the same for you....

How are you applying the product? Directly to the pad or a strip on the paintwork you pick up "on the move"?

On flat surfaces I was applying it to the paint and picking it up. On vertical surfaces I was applying it to the pad.

Try to work in the shade or garage if you can. I know that's not always possible...

I'd clay the paint first. How does the paint feel after the clay? Should be smooth to the touch.

'Prime' the foam pad to begin. Add a bead of product to the panel to pick up as you've been doing and buff a small area. Maybe 12"x 12" max. Use a lower speed on your rotary and move slowly over the area keeping an eye on the area as you go and keep the pad flat against the panel. Don't overwork the product. Try one section pass and check your results. The idea of the M80 is to hydrate the paint and that should make the paint more user friendly for a next step compounding with M105.

Just thinking here, but you are using a clean, dedicated pad for M105 and a different one for the M80 right? Have you used a rotary before and if so, how we're your results then?

WAY TO MUCH PRODUCT.

This is the most common mistake,
You only need a few drops AND THAT'S IT.
I maybe use a couple of onces of product for the whole car

Yes. Typically I use a wool pad with M105, this was the first time I tried a foam pad. I've had great results in the past with the wool pad.

If this is happening very quickly with M105 on older, neglected paint then it's likely down to simple compatibility issues (or incompatibility, as the case may be). M105 is a much drier compound than a cleaner polish like M80 and as such, on badly dried out paint, any lubricant it has can quickly be soaked up by the paint itself, leaving a gummy mess. Personally, I've only experienced this first hand a couple of times, both of which were on what could only be described as "dried out, neglected paint". In once case M80 proved to be a dream on the car, in the other Ultimate Compound did the trick.

What it really comes down to is that there is no one single product that works "best" in all situations. Some paint systems are just a pain no matter what you use on them. We've seen a lot of reports of new Subaru (2013/2014 models) having paint that won't let go of anything. You work the product and everything seems fine until you try to wipe it off, and then it sticks. And it sticks big time. And it's across the board product wise - name a brand and we've probably heard of it having this issue with these cars. Our COO here at Meguiar's has a 2009 Jet Black BMW M3 coupe and it does the same thing. M205 sticks like glue to it, and normally M205 is just a joy to work with. Not on that car. But it's not just M205, it's almost everything. Crazy thing is, we've worked on plenty of black BMWs and never had this issue with any of them, so something weird is going on with this one car. Strange things happen in this game!!

So, what's your solution? Even though you're working with a rotary, give Ultimate Compound a try. We don't normally recommend it with a rotary, but we know plenty of people who have used it that way and, after all, it is derived from M105 but in a wetter formulation. If that doesn't work, we would recommend our DA Microfiber System on a DA buffer.
