Hey anyone had this problem . I wanted to beef up my styrene armor . The crotch armor ( as it is under some stress ) tends to crack and split when bending etc . I thought I would use some of this truckbed spray on liner to beef it up . I sprayed it on kinda thick ( maybe that was the problem .. too thick ? ) and left it to dry . When I came back 5 min later the stuff was running in 1 big blob . I quickly layed it flat and smoothed it out ( tradagy avoided ). Then a couple of hours later I checked it to see how it was doing a noticed the paint on the good side was bubbling aaaaaaaaaaarrrrrrrrrrggggggggg . I also noticed that the styrene had gone very soft in some spots . I'm hoping with a few days when the truck liner has a chance to really harden so will the styrene . Heads up !!
