[font="times new roman, times, serif"]I have been doing a lot of reading here on the forum, lots of cool topics and I am learning a ton. Thanx for that. My question is does anyone buy and try any other products out there? The guy for shop Velox is all over the place with his stuff not to mention all of the other folks out there with their products. The guy from Velox did a graphite test comparison of 5 different types and although it was neat to watch not sure if it works and so how much money do we spend finding out what is actually the best to use? it would be interesting to see one of DD4H's cars go up against the Velox top car???[/font]
