so am i ok with the filler ive already laid down and just use the etching primer on the remaining bare areas...cuz like i said i didnt put any on before i laid down the filler.. now i know i need it but nobody is really answering the question at hand...do i need to knock off the filler ive already put down or can i leave it...
no you dont need etch under your filler..the filler is designed to adhere to the bare metal
^^^^^thanx for answering my question...now everyone can argue about epoxy or etching have fun guys...
why can you not spay etch over body filler? I've done it several times with not problems....
