I will be the first to admit that I do a poor job of keeping up with waxing my car. Frankly I hate doing it but I realize the importance of having the protection especially now that I'm moving and my car will be sitting outside. My question to you guys is what is the longest lasting sealant (or wax) I can get at your average parts store? I don't care about how it looks but it has to last a long time and it can't be something fancy only found online or in the big city.
