Over the years I have accumulated quite a collection of wood freight car kits. My question is this: What is the best method for sealing the wood?
Kit instructions usually say to give the wood a coat of sanding sealer and than sand with steel wool. Repeat several times.
They do make a sanding seal thinner. Do you thin the sealer like paint? Can it be airbrushed?
