Well, I must say that the G2 Caliper paint is 110% better than using spray can Hi-Temp stuff, it's night and day difference in the product quality. And yes, I used the spray can method on my previous 6 and it lasted about 1 year before looking like crap. With my new 6, I decided to take the high road and spend the extra $$. Glad I did. First, I live in South Florida and G2 recommends applying the product between 56-70 degrees, that's rare if never where I live. It states once mixed you have approximately 3-4 hours of usablilty time to work with, less if it's above the recommended temps. The most important thing is to make sure you have your car completely jacked, all four wheels off, brakes cleaned and prepped before getting your paint ready. FOAM brushing is way to go and you can use a small craft brush to get the hard to reach areas. The spray paint method took several coats to get a even coloring and still showed the rough texturing of the brakes. The G2 product goes on nice and thick and by the third coat, your brakes will take on a hard, smooth surface, similar to a powder coat. I just keep shaking my head in disbelief about the difference in product quality and the finished results. Also something to note about G2, is there 100% Product Performance Guarantee. If at any time during the life of your car the paint should flake or chip off, simple provide proof of purchase and proof of failure to G2 and they will replace the kit at no cost. I dont think I've ever heard that mentioned by anyone before. Thats my two cents... Zoom on.
