I sprayed the Lizard Skin (sound and heat barrier) on the floors/trunk of my Chevelle and it turned out nice! I didn't prep it well and used an acid etching style primer on top of the prepped metal. I may still put something on top of that for additional barrier....
On 2 of my work trucks (Tundra) that get tools put back there and I would say not very abusive on it.... the Raptor liner was sprayed on there. Followed the instructions to the letter.... and bought all their products.... even let it sit an extra week after spraying to be extra cautious.... the product is not very tough as claimed. The coating chipped very easily and simply didn't have any real thickness to it. It didn't seem to adhere well to the fully prepped surface that I spend hours trying to make right. Rhino Liner in that instance is a much better product. I would never recommend Raptor liner to anyone that wants to use it as a bed liner.
