So i decided to repaint my car, i sanded it all the way to the original primer with 150 grit sandpaper and now my friends tell me i only needed to sand the clear coat off the car… Did i just make the situation worse? can i just apply primer, sand and then paint…. can someone please help…
My questions are:
Do i need to prime over existing primer or just prime the spots where i went to bare metal?
What sand paper should i use to prepare for paint?
Any help would be really appreciated !
you need to prime the car. cant paint over those 150 sand scratches. prime the car then wet sand with 600 and paint. of course thats just basic info. give us some more info about the paint you are using, color, etc and we can be more specific with exact steps. some colors are more forgiving than others
Thanks for the reply… I am using black Omni single stage paint. Should i wet sand before primer as well? Or should i primer and sand few times before paint?
not sure how much bare metal is showing but you can probably get away with just a couple coats of a good epoxy primer over the whole car, block it with 400 and apply your single stage. 600 would be fine for a metallic basecoat but a black ss 400 will work just fine, be faster and get the car flatter. no need to wetsand before the epoxy. the 150 scratches are fine. if you don’t have alot of metal spots then you can hit just those with epoxy or a self etching primer then apply a 2k urethane primer over and block that the same way.
I would take it down from 120 to 220 and then finally 320 to get all of the heavier scratches out.
After 2K primer has been applied, block with 320/400 and then 400 orbital and finally finish in 400 by hand,
you could go finer but its a solvent black and should cover decently. And as said, yeah i guess you could go with an epoxy primer aswell if its needed in your situation. its the ultimate in corrosion protection for sure, but the only time ive ever seen it used other than in school was for a 67 vette resto because the guy insisted on it.:dnc Thank all of you guys, i kinda used a bit of everyone’s advice and it came out better than i have expected, i guess it’s true that everything is in the prep work. I will post pictures later, thank you guys !:cheers
