(2k epooxy primer & 2k urethane acrylic filer question)

[jadeydrag0117]

so bought 4 du-ppont high quality primers from the autobody supply store a few weeks ago , thinking that all four were just 2k epoxy primer.

it turns out that 2 were 2k epoxy primer and two were 2k urthane acrylic filler...

so i sprayed my bare metal and bondo areas with the primer and then i sprayed another layer using the filler

...is it ok to spray filler over the primer??!

yes its ok, but not recommended as the filler won't smooth out like the primer will. you could end up doing a lot of sanding to get it perfectly smooth

thanks, yeah i just read an article that it is adviced to do it.

and as for the having to sand alot its k i got nothing but time and 800 grit so idc

800 and a good orbital sander would make it quicker but will take still be a bunch of sanding

hmm

i rather hand sand , so i guess that means it will take extra long..

i feel that an orbital sander will mess up the prime job.

but for the most part and at the very least, the primer sprayed on pretty smooth already and i just scuffed it down with some scotch bride pads

feels pretty good
