If I remember correctly it was around $40, well worth the money IMHO. The roundel stencils masks are numbered and have a center mark so one just lays up one circle, spray, let dry for a day, another circle, spray, etc. Gary at getStencils, know his stuff and had scale suggestions (like the letter B is a bit larger, etc.).
I was getting impatient and tried removing the stencil mask after 6 hours and the latex would lift, best to let it dry 24 hours, and it was hot this weekend 99F.
I not the detail - finishing type of modeler - the stencil masks really helped me out. Looking back I should have got Gary to cut out the nose art stencil masks - but I was not looking that far ahead, a buddy got the stencils masks for a TFp47 with nose art and the nose art came out really well. cheers - ken
