I have just returned back to making airfix kits as being disabled I need somthing to ocupy my time and to keep my hands active, it has been nearly 45 years since I have attempted to make any form of modelso I have to get use to putting the fiddly bits onto the models. I am using Humorol Enamal paint and thier dedicated brushes and I am wondering what to clean my brushes with? I lookforward to hearing from anyone who can help. Phil
