I just bought a '70 Olds that has a number of scars on it where the paint has bubbled and flaked off. They are all now rusted. The car is going to sit for several years while I finish another project but I don't want it to get worse.


I was going to grind the spots down to bare metal but then what? Should I use an etching primer or spray POR 15 over them or...? At this point, I'm only interested in preservation not appearance.


Thanks

 

I would go with Por15. Of course this won't help much if they are rusting from the backside. DO NOT get the Por15 on you.

Thanks for the response. I will use the por 15 as you suggest

 

In this particular, rust inhibitor must be used after sanding rust. (source)
