79TransAm
Sorry for my laziness for not searching for the answer.
Here is the situation. I'm restoring a 79 Trans Am. Bumpers are in great condition, just faded and rough.
My plan is either A- sand with 120 and finish with 180 DA. Shoot a coat of adhesion promoter then 3 coats of medium Epoxy. Then 2 coats of urethane 2k regular build primer. Block to 400, sealer bc cc. IS that right?
OR
can I skip the 2k, then put 2 more coats of epoxy and block to 400. When ready for paint, sealer. Will this crack? Seems to be a chip resistant attack. ANY thoughts based on experience? Not too worried about flex agents unless needed for epoxy. If it gets hit, will need to be done anyway. Thanks
