Thanks for you replies guys. We used the water based paints that came with the kits. My son is very keen to crack on and get the decal stickers applied but I thought it just didnt look quite right. Seems a shame to get so far and rush it. I know its a simple little kit but I think we have both enjoyed the time. I will pop along to my local model supplies here in Norwich and see if I can get 1 or 2 new colours. Thanks Scott
