an epoxy primer will have the best grip for F/G. Verify that it is specified for F/G use. I use SPI epoxy primer and it is very strong and durable. It is specified for F/G, in addition to steel and aluminum. Results are obviously contingent upon the cleanliness of the prep. Be sure to leave enough time for solvents to evaporate before spraying. F/G will hold the solvents longer than metal.

That is one exception that I forgot about.
The intersection fairings that are available for all models except RV-14 do not have gelcoat because they are designed to have additional glass layers added during installation.

Thank you Larry. I will look into SPI.

I use epoxy resin but I hit it with a heat gun to get it to be thin and runny, then paint it on and squeegee it off. It fills pin holes and any exposed weave and any dry micro porosity. Shine a light at a very low angle to the surface to expose voids, pin holes and other irregularities. Lighting is critical to good surface prep and painting.

You can also use a high build primer and rub it in with your fingers, but I like the epoxy method. It is a one stop sealing procedure for everything.
