I am not going to get into the bed liner issue. I will say that I spray GatorHyde which is much different than the brands you mentioned. If you want my opinion email or call me. I would be more than glad to explain all that I know, but don't want to get into a brand issue on this board. My email is:
GatorHydeofDenver@gmail.com or you can call me at the shop 303 280-3056.
Yes they sell the reclaim dust deal for the blast cab. Gonna see how my shop vac works before I buy a new one. My build is on hold until the powder coat oven is finished so I can PC the 12 bolt rear end. 600+ hp 496 BBC is being built right now by Smith Racing of Denver.
