As you can see, there are still bits of paint I'd like to seal and also prevent any further cracking of the wood, etc.
Best way to seal?
I found this old frame and I'd like to hang it. It was dirty so I scrubbed off the lose paint (didn't want to remove all, just the lose stuff) and washed with bleach/dish soap (wanted to kill any mold, spiders, etc as it was in a basement for years!). I'd like to seal it somehow, but don't want to change the appearance (make it darker, shiny or anything like that). Would polyurethane change the appearance? Other suggestions?
