I bought a couple sets of these for my 54mm rockets with the ACME fin can, the stand off type. One will go on phelonic tubing and the other on fiberglass. Sharon is putting a set on her fiberglass Jart too. Wondering if anyone has any tips on installation? I'm planning on using JB weld and have scratched up the bottom surface of the guides, just not sure if any prep is necessary on the fiberglass. Not much for instructions in the package.
