im currently working on my body pieces one piece at a time. im going all the way down to bare shinny metal ( sanding, blasting ) then im spraying etching primer. im just setting these pieces to the side for now, so is that anything else i need to do to them? anything else i need to spray on them to keep them from rusting or anything?
I like to spray with a urethane primer and let sit for a long period for two reasons; one it is moisture resistant , two it gives the primer time to do any shrinking it may do before a final sanding. Don't take it as gospel when the can says "non shrinking formula".
What about etching primer followed by a urethane primer? I'm at a "lack-a" knowledge about this stuff, and just because I'm rattle canning it, doesn't mean I don't care about "doing it right". I figure Rustoleum Primer will never make it onto my truck, but I have used the etching primer on what I've done, followed by top coats ASAP. On the external body parts, I want to use a sanding primer, but don't know what would be best to go over the rattle-can etching stuff. Any ideas? ...and many thanks!
well im not anywhere ready for final stuff. i will be taking it to a body shop for that stuff. im just removing the rust and old paint and really just wanting to set the stuff to the side out of the way, but dont want a rust problem again. that what i want to know......if there is anything else i need to do beside etching primer. please help me please lol
Primer & Rust Be aware that the nature of primer means your parts will rust again unless you use Rustoleum or other sealing primer . I don't know if Rustoleum is a good primer to use on auto work but it sure as heck retards rust from coming back . Just wait a bit , we have several experianced Auto Painters here who'll have the straight dope on your question shortly .
You make a good point, Nate... Maybe I'm wrrr, wrrr, wrrro, wwwrrrrrong? I would LOVE someone with more knowledge tell me what I should use to get the best rattle can job! PLEEEEZE?
Here's what I've used I just got done with both of my bedsides recently. They were pretty pitted on top of the rails and along the stake pockets. I used a combination of 3-M scuff pads, wire wheels and selected sandblasting. After I got it to bright metal, I used a product called Jasco Prep & Prime. It basically re-acts with any remaining rust and acts as an inhibiter. It is suppose to also make primer and body filler adhere better. After applying it according to the directions, I primed with etching primer. Here's a link to the site. www.homaxproducts.com/products/surfaceprep/22/index.html
I don't know anything about etching primer... but I use epoxy primer on bare metal..... it won't rust through and you do whatever body work you need to do right on top of it...... then I shoot 2K primer and let it cure for a while.... then wetsand it and paint it.....
Lakka , Lakka , Lakka...... Zig ; Not to worry ~ if you're using Foo-Foo cans you have a lot of lattitude to experiment with . Rustoleum can be laid on in many thin coats to work up a nice smooth finish and have a good shine too if you want it , there will be no rusting problems with Rustoleum paints . Jasco products all use Phosphoric Acid to neutralize rust without damaging good metal . I use thier stuff too .
i'm leaning towards rustoleum myself, zig!! lacka lacka lacka!!! with a few brushed on letters on the doors!! jon
