I redo trunks too. I scrub them with clorox and soap, just throw it in the trunk and scrub away. No one knows what was in there or where the trunk was. If they could talk and tell us, it would be nice. I usually do it outside on a nice airy day, I hose it off and let it dry. Then I finish the outside before I start on the inside. Anyway, I do a cross-stitch like for my dauther's 16th B/D and then one for a wedding, and line the whole trunk with the pre-quilted fabric with the nice upholstery trim, and place the cross-stitch in the lid. I use wallpaper paste and it works good, no marks. My daughter is now 46 and her's looks brand new. I have 9 on my backporch to redo, some are washed ready to finish. I did one for my son's wedding, one for a 25th anniversary. I just love to work with that.
I am in Wilmington, DE and have seen some already refinished and in the antique shoppes, at $495 each and were selling. I would teach it too if I could find the people with the trunks. I hate to give mine up. There is a place in Texas that has the parts if you are missing some.
