Then you haven't heard the saga about fixing up some crows feet on my XF bonnet which ended up respraying the whole thing with a poxy Wagner airless gun because I don't have air. The high, or low, point of that was when I'd finally got a decent coat on it and went inside after telling my kids to keep away from it, then coming back and finding a couple of foot long deep grooves in the dry paint which were exactly the size of kids' fingertips. After giving them the third degree for a while, and probably scarring them both for life, I worked out I'd dragged the gun cord in the paint when leaning across to reach the middle. Fark! Fark! Fark!
