Since you're using a DA it may well be that you're using too much M105 and maybe not working it quite long enough. M105 can be very finicky on a DA, especially if you're dealing with very dry paint. In many cases Ultimate Compound is a better choice as it was designed for DA use and provides a much longer buffing cycle with that tool than M105 does. If you've got some M105 that has sort of gummed up on the surface, try spraying just a little bit of plain water on it, then put just a couple drops of M105 onto your polishing pad and go over the area quickly to break down the gummed product, and wipe it off immediately. After that, use M105 very sparingly when working with a DA.

Mike,

I had heard that you can use a little quick detail spray on the D/A pad to rejuvenate M105 when it starts drying to quick. Your thoughts?

Yes, you can do that, but you can use plain water too. It is really important to remember that M105 was originally designed for use on fresh paint with a rotary buffer. Because of demand we tweaked the formulation a bit to make it a little more user friendly on the DA, but we could only go so far in that direction without significantly altering the effectiveness of its target use. If you're working on an older car with very dry paint it may well pull all the lubricant out of M105 and cause it to almost gum up on the surface. Personally, I've had this happen to me just once, but it was pretty severe. M105 was all but unusable on that particular car. In fact, M80 Speed Glaze was sufficient to correct that car, and M80 is a whole lot less aggressive than M105. Would a little spritz of water or QD have helped the M105 on that car? Nope. It really was that severe.

But before you start experimenting with spraying QD or water, try backing way down on the amount of M105 you use. On a fully primed pad, when working with a DA, you may find that just a few drops of M105 is all you need.
