I've picked up a set of CDS Lettering dry transfers for an On30 boxcar. I'm familiar with the method of burnishing a set of these onto a car, but I'm still looking for any handy tips. The car is a wooden sided type. Might there be any specific problems that anyone has run into? Is it mostly a case of doing a really, really good and thorough job of burnishing? Should I start with a coat of glosscoat, or can it be put right onto the current matte-like paint? Any and all help greatly appreciated. Thanks.
