POR 15 or seam sealer first?

[dynolou2]

Starting my winter project, my 62 Hawk. I've got the trunk cleaned out and wire brushed, some of the seams where the trunk floor meet the side walls, had cracks in the seam sealer. My question is: do I paint on the por 15 or reseal the seams then paint over them? I have used small grinder with wire brush to clean up rusty areas, I also need to scuff up the old paint to get por 15 to stick, will scotchbrite do the trick? Thanks for your help Lou Cote [8D]

Por 15 first. That way what is under the seam sealer is protected too, then finish it with color. But before you do anything else, feather edge the areas that you have wire brushed to a smooth surface, scotch brite with a rough pad previously painted surfaces, then Por 15, seam seal & color coat.

You might reference the thread I started about POR 15 a couple weeks ago. Apparently the preparation is extremely important. POR 15 rust treatment is a 3 step application, using a metal cleaner and a surface preparation product prior to painting with the POR 15. But maybe you already knew that.
After reading the posts and on the POR website I ordered the products and am awaiting delivery.
Good luck.

POR 15 works well, but only if you follow their directions. None of the steps are optional.
Where I've used it on rusted surfaces (after wire brushing) it has stuck.
Where I've used it on bare steel that's been prepped with their Metal Prep acid, it has stuck.
Where I've used it on a sanded down paint, it has peeled right off!

A friend of mine collects Land Rovers from the 1960's. His current daily driver is powered by a Perkins diesel and is apparently quite rare on this side of the pond. He used POR 15 on the fuel tank following the directions, and was quite satisfied with the results. Some months later the exhaust pipe broke next to the tank and he drove it that way for a week - about 300 miles. When he replaced the pipe, he was surprised to find that the POR15, where it was exposed to the exhaust fumes, had come loose. It was still there and in one piece, but sitting loose on the tank. Anyone else had that experience?

I've had it come loose on the frame in the engine compartment after cleaning, prepping, and POR15. All were their products.

Try Rust Bullet. So far it seems to do a better job and I think it's easier to work with.
