One of my customers gave me a sample of his new line of car detail products. He gave me some bulletproof sealant, which is just a synthetic sealant. I used it on my wife's tahoe and its held up for 6 months now. I ended up putting some on my corvette and trans am after a good clay bar and some Menzerna final polish and it looks really nice. Some of my other friends have tried it and have had similar results.. I've used everything from Meguiars to Zaino.. This is the only product I've found that has the durability of zaino without the hassle. I thought I would share my info with you guys and see if anybody else has tried it?
