Help with redneck airboat...
Hey guys. I am building a float/boat to attempt to retrieve my deadsticked airplanes. It may not work but I just wanted to give it a shot and figured it would be fun building. Here are some pictures below of it. I am almost finished but being that I built it from balsa, how do I water proof the balsa? What can I coat the wood with so it doesn't swell/rot.
