Thanks Gary...
unfortunately I ordered the same stuff from amazon few days ago and it turned out to be a generic version, more flimsy and not as thick.
I think that if I use it on my p-51 it will not show properly after few coats,of paint are applied.
I need the original stuff, and I think I just found some on eBay even though is yellow in color which it should not make a difference since it is going to be painted and then removed.....
thanks for your help bud!
