Sealing antennas

[rodsmith]

I have a com antenna mounted on my wing. It came with a gasket, due to the curvature of the wing, there is a small gap at the rear of the base. Need ideas on what kind of sealant to use to keep water out. I don't like the idea of anything with silicone in case I ever need to do some paint rework. Guess the same applies to all my antennas.

I really like to use pro seal. There are other less expensive sealants but pro seal has always worked very well for me
