What do you guys and gals use to protect parts that you have fab'd up or small stock parts you have cleaned and sand blasted knowing that in a few weeks or months you will be spraying epoxy primer on them or other automotive primers? I have used Gibbs and I like it but I'm talking about a spray bomb type primer that can be sprayed on to protect the part from rust and not have to be removed before spraying better quality primers. Thanks Mike
I've been using a spray bomb can of axalta 410A primer. I really like this stuff but it's not cheap, around 50.00 a can. What I like is it dries fast and I use it on parts I'm going to use spray paint on, in my case, suspension pieces. But I'm building a driver not a show car. My frame I had powder coated but the suspension I wanted to be able to touch it up easily. For a test I took several new 1" bolts and knocked off the plating with a power wire brush, wiped them down with prep-sol then primed each one with a different spray primer, rustoleum, duplicolor, and this stuff. I sprayed them at the same time, waited 24 hours then I sat and with my finger nail (my nails are tough, lost many several times) and after a few minutes I could scratch the first two primers off, the axalta I could Mar but not remove. And I like the fact I can top coat in an hour and I do... ....
I've used Gibbs for years with no problems down the road when I'm ready to paint. I just sold a fresh bare metal deuce highboy roadster that had been m***aged with a DA & Scotch pad then wiped down with Gibbs and it went to Florida stayed rust free.
Most ordinary primers are porous and will still rust tho you might not see it 'til you sand the primer off. Gibbs is also my go to anti-rust for bare metal. Dave
Cody Walls, who lives near the ocean, did some tests and Bulldog Adhesion Promoter won. Gibbs was one of the products in the test. It's not cheap but it works. https://www.amazon.com/dp/B005IUBMS6/?tag=atomicindus08-20
