Two questions: 1, Since I've been working off and on my project for 40 years if I sand & prime a part it might be awhile before I get to it again and by that time, it's rusty again. How well does this stuff work to preserve things before I get back to them? 2, What kind of paint/primer do you use when paint day finally comes? It would be nice to prime as you go and stack things in the corner until it's all done without having to de-rust it all again.
I have never used Bloxide so I can't say about it. What I read on the Eastwood site
revents corrosion of coated steel surfaces for several months
of outside storage. It costs $75 + shipping for 1 gallon of sprayable material.
SPI Epoxy cost is $80.85 per sprayable gallon with free shipping and it will survive being outside in the weather for 5 years or more.
If you are going to sand and prime a part and let it rest for a day or a decade I would suggest SPI Epoxy primer directly over the bare metal after being cleaned with SPI 700 w&g remover. All it will need at a later time is a good scuff with a maroon scotch brite and a fresh seal coat of SPI Epoxy.
I have used various weld thru primers and now just prime with the SPI Epoxy then where I am going to do a plug weld I use a small wire brush in a drill and spin the hole and backer clean in 2 seconds.
