we are 99% sure we're going with Raptor, it's available locally and we like that you don't have to use it all at once..
anyways, how much did it take to do your tub and how many coats did you do? The kit the dealer here has is 4qts in the 4 bottles. The CS we used in the tub only took 1qt for 2 coats. I called them today and they have 1 kit left in stock so I need to go pick it up tomorrow, but he said there was a possiblity that he could break it up and sell it cheaper if we didn't need all 4. (they install it there at their paint shop also, so I'm sure they could use it if we don't need it, benefits us both)
