Thread: How well does primer hold up and for how long?

Tweet

The truth is, the parts needed to be striped or blasted. I got as much of the surface rust off that I could, but I needed to put the truck together and get it out of the shop for a few months for a job I will be doing. I primed the parts today.

Whats done is done. My plan now is to spend the time to find some of the parts that need replacing, then re do the front end sheetmetal. I will be blasting all the parts at that time, so...

between now and then, should I put a coat of rattle can paint on, or will the primer be ok, for a few months?

Thanks, you guys are very helpful.

Click on the camera under my name and look at my truck,it has rustoleum rusty metal primer in the quart can and red oxide ratlle can applied very thick and its held up for over a year.I have sanded a couple of spots over the last year to look for rust underneath and so far there has been none,only where I applied it thin on the edges......so I just sanded the rust off and applied more in that area.Actually its been more like almost 2 years

I think you have the key to the whole thing there Shawn, "applied very thick". The problem with the rattle can is it is VERY thin ( viscous) with little body and a few coats may not give you the film build you need. ALSO, on the edges and stuff, it is VERY easy to apply a coat and it LOOKS like it is covered well but it is so thin there is no protection.

All I know is, if you are going to strip it anyway and prime it properly after driving it around a few months this is all a moot point anyway. A few months in bare metal wouldn't be a big deal if you plan on doing it up anyway.
