Greg, I found just about the opposite. That the gel coat would start to oxidize faster than the vinyl would fade. But, so long as it all gets protected on way or the other, all is good.I used the gel on my vinyl hot tub cover. After 5 years of sitting in the sun all day, it still looks great so the thinking is vinyl fades before fiberglass so why not try it. I liked the results and kept using it.
