May be different types,but I have good stick on with a few ties and work great. ISP is good stuff but exspensive. If you have the money go for it if not go with the other. I have used the stick on in Sprint Car,Late Model and modified dirt cars with no problem. There is good stuff out there and there is crap.
I use Longacre and it forms great and looks great . Check it out Motorsports of KC in Kansas City ,KS
