Epoxy paints

[jerseydriver820]

I'm looking for some advice. I'll be doing some work to my BMW, welding on the chassis and the interior. I'd like to finish the process off with an epoxy paint. A lot of people use POR 15 but I have reservations about the product. It also will look bad when finishing the interior. Does anyone have any recommendations on a good epoxy primer and final product to use. I don't have a spray gun but could get one if needed. It would be ideal if I could get the product in a rattle can. Just seems easier.

Any additional advice would be greatly appreciated. I can weld but I have little to no experience painting, especially painting while on my back lol

Process would be:
Wurth Weld threw primer on surfaces
Weld
Seam sealer? is this even needed if I am painting?
Epoxy primer
Epoxy paint

For reference the job is an E46 M3 Rear subframe reinforcement

For under carpet use and chassis epoxy, I like Rustoleum 9100 series. Use a brush or buy a cheap HF HVLP gun to spray with it. No primer is necessary, just clean, solid seat.

Second option with be a Hammerite type paint, but they aren't smooth in the final finish. But under the chassis and under the carpet, who cares.....

I have had issues with POR adhesion. After cleaning and prepping it still came off in sheets after a few years.
Ever heard of ZeroRust? It's less glossy than POR but works better for me.

Same here. I gave up on POR years ago. Followed prep instructions to the tee using their products. Always looked and performed great for a while then started delaminating.
