Johnny,
You may want to hop over the the RC Pattern Forum for additional info on painting models. Pat Harris, (AKA Portlandflyer) is a superb source of valuable information which he describes in detail. He posts on the RC Pattern forum. Also check out MTK, posting on the Classic Pattern sub forum. These guys paint with a gram scale nearby to minimize weight build up and still achieve a fantastic finish on their 2M+ pattern models. Also, LGM Graphics posted some painting tutorials on this Jet Forum but this was a while also and may take some digging to find. Good luck on your painting quest.
Rgrds,
Art ARRO
