Wet sanding, final grit?
Ok, sanding down a car, miata, bumper covers and fender. Will be painted while off the car. I am not sanding to metal or bare plastic. When wet sanding and preparing to do the final sand what grit of sand paper should I use to best prefare the surface to hold the paint the best. Assuming everything to this final point was done correctly what final grit should I finish with. I am not sanding to bare surfaces so I was not planning on priming since the orig paint is still there just sanding down.

if your doing a scuff and shoot, then your last step would be done with 600 grit. 600 after 320 works great on primer, but for paint that is in fair condition i use red scotchbrite pads. scuff it dry, or with a 3M scuffing agent available at most paint shops. good luck and post some pics.
