I used masking tape for mine painted with a semi gloss thru the airbrush. only used the tape edge as the overlay seam as making it to pronounced made it look to out of scale to me
Alan, modelroundup arent to bad with their shipping but I found Hobbylink Japan to be slightly better with the best prices. Andy at scaleautomobilia (sp) isnt too bad either
I also think the skull white is probably the best paint ever for whitewall tyres. Its just off a pure , like a slightly aged white. Washes are brilliant.
