Q: I have a truck frame that still has a lot of factory paint still on it that I know won't last very long. Do I need to strip all the paint off first or and can I go over it with the self etching primer and then coat it with rust seal?

Asked by:  - 3/8/2014

A: It would be best to strip off the old coating, but it is not necessary. The best rust protection is always achieved by applying RustSeal to properly prepped metal. But, if you have do not want to strip off the old coating, you can clean the old coating with KBS Klean and scuff it up with 300 grit and then apply RustSeal.

I am repainting a 1958 chevy impala and I used the rust seal and this fusion primer and it all worked just great. I would highly recomend it and already have to a few others.

Rating Perfect for Metal Toys
KBS Fusion Primer goes on smooth and even. Even if I spray a layer that is too thick, the primer tends to level itself, reducing unsightly run marks. Sands easily too.

Rating Looks Tremendous
I painted a 454 block, heads, oil pan, and manifold and it looks tremendous. The blue and aluminum color went on easy and I applied it with a brush without removing the engine. The product went on easy and even, however, you have to take your time and don't rush it.

Rating Best metal primer I've ever used!
I've used this product on billet aluminium, copper and brass. No complaints. Follow the simple instructions and you get great adhesion with consistent thickness. Accepts enamel model paints beautifully.

Rating Very Impressed
I am building an experimental airplane and am using the Fusion self-etching primer on the smaller part. I'm impressed how evenly it goes on and the end result. You've got a good web site and your order turn time was excellent. I'm sure I'll be placing additional orders in the future.
