This question has no doubt been asked before,but I can't find anything on the forum.I'm looking for a suitable thinner for airbrushing Humbrol,Revel and Xtracolour enamels.I've been using Revells thinner but at 4 quid for a small bottle there must be a cheaper alternative.I use White spirit to clean my airbrush and have tried using that,but it seems to take much longer to dry.I've heard of cellulose thinners being used with enamel.But it's quite volatile and I don't know if it will attack the paintcoat you spray it onto.Has anyone tried kerosene or turpentine?.
