I'm buffing a boat and having an issue where I'm working the machine/polish and globs of polish fly out and quickly dry on the surface. It's hard to remove. Other than that, I'm pleased with the finish.

More info:

8" 3M black waffle foam pad
3M perfect-it polish #2
Working at night with halogen work light 3-4' away.
1500-1900 RPM
Pad was dirty, cleaned it, same results.

I tried applying product to pad in large drops and a swirly line. I spread the product before turning the machine on. I start at 1000rpm, spread it around and then ramp up speed. Trying to hold pad flat as possible. Maybe I'm lifting and product flies out?
 
Sounds like your using to much polish or the surface wasn't
perfectly clean before starting.

Thanks for the reply.

The surface was clean. I hit it with 3M super duty rubbing compound and a wool pad.

Now that you mention it, I'm probably using too much product. What is the proper amount? 6-8" line for 2'x2'? Apply to pad or surface?
 
IF you look at the design of the waffle foam pad it lends itself well for product escaping unless it's fully compressed against the surface.

Maybe try a flat pad see which one works better for you?

That or apply more pressure when buffing and keep the high portions of the convoluted design compressed to basically turn the pad into a flat pad thereby trapping the product against the pad and the surface instead of letting it escape as splatter sling.

I've found 3m products to be a bit messier than some others. It is more liquid, so I use less of it than I would a creamy polish. Try much less polish to start.

3-4 dime size drops is all you need. This also depends on the product some
have a longer working time so you don't need as much.
 
Thanks for all the tips guys! This all makes sense, I'll report back in a few days due to rain in forecast.

Really good point.

Last night when we compounded the Model A we we're running our rotary buffers around 1000 RPM

About the only materials I know of that like high speed are gel-coats and old school lacquer paints.

Thanks, Mike. I'm working on gel-coat.
 
Along with all the tips above, I used a hand applicator to spread product on gelcoat and also misted the foam pad on rotary.
