you been sniffing the glue again painless?
I am still using a brush to paint but hope to get a spray gun soon.
I put on a surface primer and it worked better than straight onto plastic- tamiya white
brush tips- thin down the paint. It should have the consistancy of milk.
leave to dry before going near it again- I use xtracolour and they take 3 to 4 days to dry
once you have done the basic paint job coat the plane in future and leave to dry- it is now safe to handle and you can put on effects. wash the panel lines, put on highlighting , smoke etc, without ruining the base paint
put on decals.
finish with matt varnish to tone down the future and seal on decals.
hope this helps
