Can I use adhesion promoter in the areas that cant be easily sanded during the wet sanding before add last clear coats?

IE; The area inside the trunk seal channel, inside the inner fender lip..etc,

Not to rush but i need to know ASAP as I have another nice period coming tomorrow and sat. to paint..

Just use some 1000grit or red scotch-brite by hand. You could probably even get away with 320 since these areas aren't often seen. 3M also came out with a gel product works with scotch pads to "turbo charge" them for these hard to get places. Most importantly make sure it's clean of dust or any residue, wax or grease then adhesion shouldn't be a problem.

oh lol , thats a good idea. Thats why I asked first,wow talk about Brain cramp. Never even crossed my mind..

Is very clean, I'll wash the car again before last clear coats. Almost done with wet sanding now.

I'll get some tomorrow.
