I'm usually a huge supporter of Eastwood products, but I cannot give the TLC Colorgard Stainless kit a good review (sorry). I used a detail gun to spray the product on my Hooker headers, re-installed and heat-cured the headers, and then removed and used a polishing wheel to buff the polish - with a '72 Camaro, it's a pain to remove-reinstall. After all that effort, the final result is mediocre at best. For the cost of this kit and shipping $49.94 (39.99 + 9.95), it's really not worth it. I also have a '69 Vette, and used a can of VHT extreme heat ceramic aluminum spray paint for the headers - they look great and have held up over the years. I'll likely re-spray the Hooker headers with the spray paint for better results.
A big disappointment - and a waste of $50.
