Doogs- Good to have you back! Wondering where can we find your completed Spitfire? I am assuming Spitfire GB. Don't be shy about posting pictures... you know we all get excited when we see new pictures.
Carl- Excellent tip for us to try. I used one of marker's cap on the 234/1 wheels a while ago and it was great. I never thought about using those electric caps for smaller wheels. Looks like I owe you another for the tip.
However I do have a tip to share with you... buy a box of rubber gloves. They are great especially when I airbrush. Remember I suffer mild case of OCD...
