I quite accidentally found a product that totally strips off SEM interior paint. Believe it or not it’s Kirker Pre Cleaner 650 Wax and Grease Remover sold through Eastwood and probably other vendors. I went to clean an interior part that I previously painted with SEM Paint. IT TOOK THE PAINT RIGHT OFF. I couldn’t believe it. So now you know if a SEM paint job messes up for any reason, it can be easily stripped and pre-cleaned at the same time.
