True.
Youthful exuberance and inexperience are a lethal combination.
Thing is, I was bringing the car over to England a few days later, so had to effect some sort of repair. I had lots of filler but not much hardener, but I reckoned if I mixed in what hardener I and and sprayed over the top with rattle cans it would go off eventually.
It didn't. Had the car another year after that and it was still like soft putty under the paint.
