My RV-4 can't fly through rain. It leaks terribly the forward edge of the tip over canopy. I've tried various seals, the latest being a V-shaped seal. Does anyone know how to really waterproof the RV-4?

Jeff, I had the same problem with mine. What I did was cut off the front of the fiberglass fairing that laps up on the forward skin. Then I covered the forward skin, very tightly, with wax paper (or use a mold release as long as it doesn't hurt the paint.) Then I adjusted the canopy to close very tightly. Glassed a new fairing on top of the old one, overlapping the front skin in an arc fashion. Let it cure closed. Then trimmed to fit, and put a seal from Ace Hardware underneath. Flew IMC quite a bit without any more leaking.

Thanks Paul. I don't know if I follow what you did. Do you have any pictures online?

I had the same problem with an RV4...I also tightly wrapped the wax paper on the forward deck. - then put clear silicone on the wax paper thick enough to squeeze out with the canopy closed. Waited overnight, peeled the wax paper off of the silicone and trimmed the excess with box cutter front and inside. Worked quite well. I was able to hose the plane down without leaks afterward. And, was not noticable.
