I use Collinite 476 paste (up to a year protection) or Collinite 845 Liquid (6 Months maybe more). To answer your question you may look around autogeek.net and autopia-carcare.com. There are a few people doing coatings, ceramic etc. on their forums. I am very happy with Collinite so no need for the other things. Another good thing to have around is optimum spray car wax which has the only patented UV protection on the market, I apply it over the Collinite every 3-5 months or may use it after a no-rinse optimum wash and wax which also contains car wax. Where I live I need all the protection I can get. I usually order from either of those two forums when they have 15.20.25% sales with free shipping over XX amount of dollars. Sometimes I will order off amazon with free shipping but no discount if I need it now and can't wait for a sale.
