Hi Guys, Like Dana Said, I am finishing up my first RV-7A wing and ready to start on the second one. All the talk about the "black death" proseal on the RV lists makes me chuckle. If you can't pound it or bend it the RV guys start panicking. You should hear them talk about the minuscule amount of fiberglass work they have to do. Hey, if any of you have an RV builder near you strike up a friendship. Help him out with his fiberglass work and you will have a friend for life. He will, in just about all cases, be glad to help you build a set of aluminum fuel tanks. It is no more of a big deal for him to help on a set of aluminum tanks than it is for you to help him out with a little composite work. Both of you already have the skills and tools.
Back to aluminum tanks and proseal. If you have built your KR tail and wings and have put up with the epoxy and or vinyl ester then proseal is a walk in the park. Mix it up in the general ratio specified and just do it. It isn't sensitive to exact ratios, just may take a little longer to cure. When used on fuel tanks it just works. Try it, after you are flying, you will like it. Besides, we all ready have our epoxy work clothes. You will just have a little black to go along with the crusty amber epoxy. After all, as of my last RV newsletter, there are over 3,222 RV's flying and they all have proseal'd aluminum fuel tanks. Have to take a moment here and echo the sentiments of the KR builders that are flying rather than modifying/building. The fastest way into the air is build it to plans. But this is Experimental aviation and if you enjoy learning new methods and techniques then find an RV builder and make a new life long friend. They just have a bunch of scars from aluminum cuts rather than epoxy rashes and allergies.
