Vid-
Let me preface this by stating I'm an idiot. With that out of the way, I've been repainting an OXO playfield almost 100%, it had planking, missing paint down to wood, scratches, cracks, etc. I have been using acrylic paints, masking areas and airbrushing one color at a time. When one color is complete I have been moving on to another color so to prevent the masking for the next color from lifting up my newly painted areas I have been spraying a clear coat over the playfield. Here's where the idiot part comes in. I just grabbed whatever I had handy in the basement to seal the field, in this case water-based Minwax polyurethane as it was convenient and didn't stink up the house.
Fast forward to last night. I'm about 90% done with the playfield and started masking everything off to spray the field color. I laid down some blue tape, trimmed as needed, and pulled up the waste. In the process I started pulling up large chunks of the polyurethane so I stopped, walked away, and read a book instead. I think i already know the answer to this question but was using polyurethane to seal between colors a fatal error? I thoroughly cleaned the playfield beforehand with alcohol and naptha so I'd hope this isn't an issue of old wax bit either way it sounds like I might be screwed. Any thoughts?
