Is that picture you posted where you are now?What primer is there?Either way,i would block it with 180 then reprime it all.You can't prime one time over anything courser than 180 and expect it not to show scratches.Steve, you didnt read the whole post. I blocked with 500 grit and sealed and some scratches re-appeared because I sprayed high build primer over 36-120 grit scratches. I created a problem for myself due to inexperience. I dont want to re-strip the whole car. There must be a way out of this.
When block sanding i exposed both bare metal and filler, the filler shows in in the sealer.
My jobber told me to reduce the expoxy 2:1:1. is this not correct?
What i do,is get my metal level as possible...apply filler,use 40 or 80 to level it out and once i get to the point where i know one more coat of filler will be it,i make the final coat polyester putty ,guide coat and sand that with 120,then guide coat again and finish with 180.Prime..several hours later sand with 180,and reprime.
