Reply to "BEST BARE METAL COATING"

Multiple sprayed on coats of two stage primer. Rustoleum primer is also good sprayed to structural steel but is very, very slow to dry and needs to be applied thick and let drip and run.

I like the 2 stage primer the best. Don't worry about being neat with it. Let it run and drip under the floor pans.

Then on the inside panels like inside the doors and rockers shoot the waxy cosmolene rustproofing. Let it sit as long as you can before reassembling. It is supposed to creep into the nooks and crannies on the seams and seal out the air.

It gets sprayed on with an undercoater type wand.

3m body shoots is a high quality dark charcoal gray undercoating better then the rest. It dries looking civil rather then looking like the original undercoating from the LaBrae tar pits that the factory sprayed in the engine compartment.

The 3m rocker shoots also works well to minimize the stone chips behind the wheels and under the rockers. It dries tan and is intended to be painted body color over it.

I have found that construction "flashing cement" dries hard like a plastic and works well inside of the fenders to absorb the stone thrown by the tires.

It needs to be troweled on and you can get it to look bumpy like a travertine if you work it a little.
