Tat2Brat Posted August 4, 2014 Share Posted August 4, 2014 Gonna prime my 83 brat soon. The plan so far.... 1) sand it and repair rust (already done) 2) acetone it clean, possibly isopropyl alcohol after that 3) prime it! 4) body filler appropriate places 5) more primer I was just gonna use the epoxy primers they have now a days cause they are pretty great but then i was looking at my brat and sanding the rust off and thinking it would be great to have the acidic part of self etching primer to get any of the surface rust that might be hiding in gaps or wherever (so hard to get it all) can I body fill over the self etch? or should i just stick to the epoxy? I googled it of course but there is alot of different opinions out there thought i'd ask you knowledgeable folks Quote Link to comment Share on other sites More sharing options...
KiwiGL Posted August 5, 2014 Share Posted August 5, 2014 If you're painting bare metal I'd recommend self-etching as it'll stick to the metal better due to the chemical reaction, but if you're priming over existing paint epoxy should be fine. Since you've sanded it back I'd go with the self-etching. One thing though, it's not a rust-converting paint - so if you spray t over rust it won't stop the rust. It's just designed to etch new, clean metal. Cheers. Quote Link to comment Share on other sites More sharing options...
Carl B. Posted August 5, 2014 Share Posted August 5, 2014 ^Exactly what KiwiGL said. Cut out all the rust first and use etching primer on any bare shinny metal. Look for a primer with zinc chromate, will be yellow to greenish color. Quote Link to comment Share on other sites More sharing options...
stratman977 Posted August 5, 2014 Share Posted August 5, 2014 No body filler over self etching primer. It doesn't adhere properly and will never feather edge. Quote Link to comment Share on other sites More sharing options...
