there are a few cracks in the paint where I am sanding. I thought it would be like repairing a figerglass crack, in the way that you must remove the crack to fix it. I have been taking the area down to metal when I find a crack or deep bondo ( 1/4 +). However the roof and front and rear pan( grill bumper areas) are good and I will only wet sand them.
Since I will have bar metal , plastic fill and wet sanded paint , do I still use the etching primer then the sealer.
Do you guy's trust the body work of an unknown person on a car you bought? I mean if you were doing this job and found the cracks and lots of plastic where the panels could have been hammered out a little if not all the way. woulden't you take it down to the metal?
