Thanks for the info guys! I'd be sure to definitely apply a clear top coat (as opposed to now where I only do that for maybe 50% of my models). I thought for sure that the humidity level in a garage, whether insulated or not, would wreak havoc on decals. I figure if I have the guy build me some nice display shelves, I'll either have them behind glass or at least in enclosed cases.
Thank you again for the feedback!
