If I cant remove the contaminants from the paint entirely, will they abrade my pads or is there a concern that the contaminant particles will dislodge during the polishing process and scratch the paint?
Sometimes, the little bumps could be the paint itself, as in a shoddy paint job or imperfections in the paint from wear-n-tear...
Clay the paint as good as you can, sometimes you may even want to shrink the size of your work area down and investing in some aggressive clay may be the best approach.
Chemically stripping can help too... some times it's a trial and error process to figure out an approach that works best and different types of contaminants will come off with different types of chemicals/solutions, (MS, IPA, APC, etc).
Once you've given it your best shot their comes a point where you just have to start polishing. Foam pads on DA machines will tend to glide over little bumps on the surface, depending upon the abrasives in the product you're using and the pad you're using, it is possible to abrade anything on the surface the clay didn't remove, you won't know till you try.
This is another reason why it's a good idea to do a Test Spot to one area and then after going through your process to this one area, re-inspect the paint in the area you worked on as compared to an area you have not worked on and you should be able to determine if the paint is now smooth.
In most cases, if you're doing a heavy correction step first, any contaminants that come off... "if" they are then ground into the paint as a part of the correction step, the next polishing step should remove any of these marks.
Another good reason to,
Clean your pad often
Alway wipe off spent residue before applying fresh product
Give it a shot and post back here what you find out...
