Just imagine if you would have messed up. Not a good thing to think about. I painted an RC car body the other day and it came out perfect. But my son watched how I used the spray can so he decided to help me when I was not there. Let's just say I had a white piece of plastic body. I had to strip the whole body of paint, I started to repaint and it's coming out ok but not like when I originally painted it. This is why he is not touching my trains. OUCH
OOOH dear! I have a 2yr old grandson. I'm thinking of buying a straight-jacket for him! Mind you, I don't want to put him off, as when he gets older, he can get "'round the back" and clean the track LOL
