Anybody have any experience with Herculiner or something of that sort? I am wondering about the same thing on my 46. I have seen a couple of vehicals at car shows that have done this - for whatever reason they were firerglass fendered. I am guessing they did it to keep the gel coat from "starring" from rocks and went ahead and taped them off on the edges as well.

I used Herculiner on all my fenders and any other sheetmetal that needed it. I don't think I would use it on the frame and expect it not to get chipped off.
