Primers

It's not a myth, it's true. The only primers that are suitable for long term exposure to the elements (i.e. long term project stored outside) are epoxy primer/sealers such as DP-90. Regular parts store rattle-can lacquer will rust the metal almost as fast as nothing at all. So if you have a long term project that the bodywork is not complete on, and you need to "hold" the metal for a long time, overcoat the primer with some cheap flat black spray paint or something.

It's true. Ask your paint dealer for the manufacturer's data sheet.

It's true.

Zinc-based primers will resist rusting better than the regular stuff, but should still never be left uncovered.

What about lacquer finish coats? Makers of car covers warn not to use their covers over lacquer paint jobs, so does that mean they can't be used on GM cars?

If only I had the ways and means to effectively sandblast my truck and then shoot it with this. I'd wetsand it to a low 'wood stove' sheen and leave it just like that. It's great stuff, and IMHO it looks real nice.

YMMV
