Ease of website

Ease of website. Initially when I started using PaintScratch I was apprentice. Their products are the best as far as my needs. Color match is excellent. Not always perfect due to years of a vehicle but even on an Audi Allroad Highland Green it was more than I hoped for. Now if I could figure out the best remedy for preventing chipping on the aluminum door blades which I prefer to be body color I would be a very happy camper. As it is now, I pull them once a year. Strip and abrade them. Use self etching primer. Resort body color. Directly from their spray can. Clear coat and they look new. Anybody have a better direction for me. Always open to suggestions. Thanks again
