Two ..he is right filler is not good directly on primer that is why we use sealer on bare metal.  |
x2. plastic filler sweats with temp. changes. if u're doing something for u'reself that u plan on keeping, u need to put down an epoxy primer to seal the metal from the filler. some use dp but i prefer southern polurethanes. let it dry & apply the filler over it. once u get the filler blocked out, then u can squirt it with a surfacer primer. i prefer k36. try to finish the filler with at least 120 if not 180 to cut back on some of the soaking-in.
