Hmm…I’ve never heard of painting a seat before. The seat surface is actually epoxy, so something that would stick to that.
If you don’t want to say publicly, can you email me the brand of resin you use? I’m sure if I get the blush off I can paint it white with a boat deck paint. If I leave a chrome wrench in the sun for 5 minutes where I live it gets soo hot you can’t touch it.
