First off let me just say I love this product, but I've found something out. I washed my car Sunday after it sat out for almost 2 days in row. Then I took it to work on Monday and it rained, rained HARD and guess what, the water didn't bead up anymore. I'm thinking there's something in that chemical that either strips the wax or just lets the water sit there. The shine was still there, but when driving home in the rain the water wasn't beading. Does anyone know if there's actually something in this stuff thats bad for wax. I'm still going to use it, just not on my Crossfire, I'll save it for those vehicles I'm getting ready to detail so it saves me alot of time drying them and thats it!
