Which is tougher and more solvent resistant?
After 20k miles of touring my frame doesn't look so good. Co-Motion charges a minimum of $350 to repaint my bike with "PPG Global System" paint. San Diego Protective Coatings will paint my frame with "urethane" for much less. Cheaper yet (but not by much) is polyester "powder coating". Nobody seems to be too specific about chemistry and I just can't find anything readable (at least to me) online.
I am most interested in toughness and second in solvent resistance. Can anybody help me? Thanks in advance for your help.
