I can only speak for airbrush Martin, and for any aerosol work, all

our paints and dope become airborne and you need protection.

I only ever spray dope 50/50 as I want a good amount on the model to seal it

With enamel and acrylic, again use the correct thinner, but not so thin.

Start at 10%

Ok, job done, brushed on a coat at about 60/40% ratio as Mike Woodhouse suggested more thinners than dope, very pleased with the result, will put a second coat on as there are a few pin pricks here and there in the weave still. Rain however has tempararily stopped play on that front for the moment, i enjoy film covering a plane and adding coloured trim but there is something special about covering with a tissue like substance and doping it, i had forgotten how much i enjoyed it! Last model i did that on was built from the same plan was fourty four years ago disgust I have another one from this plan to build for a diesel and a similar sized GeeBee Model D to do for electric, all will be covered in Polyspan and doped with an acrylic paint finish smiley
