Got the frame sanded and painted today. Used appliance enamel (white). Supposed to be super hard so we will see.
Sprayed with a Preval sprayer and I highly recommend them for something bike size or small projects.
Gun with 1 cartridge was $5 and spare cartridges are $4. They claim to spray 16oz per cartridge but it was more like 10-12.
I used about 1.5 cartridges for the frame and forks. I'll get some pics up as soon as it drys.
