anyone ever gelcoat over body filler?

[WEtakinOVER]

i came up with an idea...... applying gelcoat over body filler to help prevent it from rusting back (over rust spots that have been repaired).... has anyone ever tried it? if so, is tooling gelcoat better for the situation?

just hoping someone has tried it before i waste my money on a gelcoat gun or fuck up my regular gun

Gelcoat is for fiberglass, I don't see why you would want to put it over polyester filler. Some people like to use an epoxy primer over repairs, but it isn't necessary.

ok, good to know, thanks
