When I initially got the kit, there were burn marks caused by the laser cutting. I didn't think it was a good look, so I grabbed the first spray can on my shelves and painted all the wood before I assembled the kit.. The spray paint was a vinyl type. It hasn't affected the wood in the kit at all. The replacement part was cut from 6mm (1/4") MDF, and I didn't have any more paint left. I've since printed the part in ABS and will fit it when I pull the assembly apart to install the bed leveling kit.
