That's how it is anytime you start a project like yours.
It starts out fixing a couple dents. Then you find there's a lot more than you think. Next thing you know you spent a $1000 on materials and 100 hours of your time.
Then after all that there's a spot or two that didn't come out well and it drives you crazy even though no one esle sees them.
Then you go sailing for the first time and capsize and while righting the boat you slip on that just polished hull landing hard on the hull with your knee leading the way. Crunch,Dent.
