So true. My dad taught me the same way. But in this case, if it works, I did it right. If it doesn't, I'm not out that much and I will probably end up taking it to the shop to get the leak fixed. The leak stop I put in it had red dye and I can't find any red dye leaking out except for the little bit at the Schrader valve.My father always taught me, if you going to do it, do it right.
