Has it done to the Foretravel motorhome that I just sold. The gell coat was dull and lifeless. After washing and then a thorough going over with TCP, 6 coats of liquid acrylic floor finish ( not Zep but a professional product with higher solids content) was applied using micro fiber cloths.
It was dry by the time one cost was done, so all six coats went on with 2 people in 3 hours (36' coach). Very, very shiny and lasted at least 6 months (sold the bus).
Just apply very thin coats. Avoid drips at all costs because they DO NOT come out except with sanding.
