Mr.Pink Posted September 26, 2012 Share Posted September 26, 2012 (edited) I'm working on restoring a 1976 280Z and am in the midst of repairing rusting floor boards. For the most part the rust didn't penetrate so I sanded it down and treated it with the POR15 Prep & Ready with good results. Now, there are two minor holes about an 8th of an inch across in the floor. Can I paint over the whole floor with the POR15 paint and then apply a body filler over the paint or should I apply a metal body filler before the paint? Anyone with experience? Thanks Edited September 26, 2012 by Mr.Pink Quote Link to comment Share on other sites More sharing options...
OldAndyAndTheSea Posted September 26, 2012 Share Posted September 26, 2012 Typical bondo doesn't like being laid over anything other than bare metal. There are other products, like polyester glazing puttys which can be used sparingly over paints, but I won't get into those. I'd clean the metal best you can, media blast if necessary; cheap devices can be made or purchased at harbor freight. Then use whatever filler. Prime that area Sand (150 ish grit) POR-15 I'm sure there are a bunch of different avenues, but meh, that's what I'd do at least. Quote Link to comment Share on other sites More sharing options...
