Wow, 27 pages! Y'all have been busy!!! Just wanted to update, I am still in love with the TCS and 4633, I've gone through 40 pounds so far, and I've successfully tested 15 FO's. Most I only used 6%, some I had to up to about 8. Ive had great results with about 10 tester's. I am completely satisfied with the blend! My nephew is in ROTC, they are having a car show the 30th of this month, I've signed up to have a vendor booth at the event. Its only a couple hours, so I'm just going to take a few of everything and see how it goes!
