I'm currently building a few old kits I bought from a garage sale, the Johan 1970 tornado tyres are pretty much useless, but a set of AMT Round 2 white walls will fix that problem, the glass will be need to have the scratches taken care of, I use Meguires 'PlastX which is really good stuff.
I also started to prepare a MPC 69 Firebird Convertible, the decals are in pretty good shape considering the kit is from 82! However will see what happens when they hit the water!
My biggest challenge will be a Revell Custom Chevy Van from 76, the body is badly warped, decals are history and the classic old 'glue together tyres' are not very good, but its worth building!
