[Fot] Frame paint

Thu Sep 28 22:08:35 MDT 2023

Rust-oleum from any hardware store will do the job.  Easy rattle can touch-up when you need it.  I think I used 2 quarts on my frame, after DP90 epoxy primer.  It still looks like it did when I finished it 12 or more years ago.  Maybe POR as an option for a slightly harder barrier.  Good preparation is more important than the exterior finish.  
What are we saving our frames from?  They are not daily driven in all climates and conditions like they were when they were new.  Powdercoating is like dipping the frame in plastic.  It is overkill.  I guess you could blast some rust proofing inside the frame rails while you're at it.  It will then most likely last forever.  
I've powder coated things like the brake master box to protect it from brake fluid, the roll cage, because it is exposed to lots of potential scratches and scrapes, and my custom made front cross member that the sway bar is bolted, because of it's direct exposure to road and track debris.  
Triumph frames had no primer from the factory.  Only a thin coat of black paint.  My car's frame had most of it original black paint still in tack.  It did have cracks near the front suspension mounts and rust through from the inside at the lower end of the diagonal spring tower support on one side.   Extra durable paint would have not helped.

I've used Rustoleum as the touchup rattle spray cans are perfectly matched to the quart cans, and you can get it just about anywhere.  POR products might be a little more durable than Rustoleum.  If the frame is bare metal, an epoxy primer is a good start, but with POR I "think" you can skip the primer.
