@gunrunnerjohn posted:Not sure I'm that wild about that choice either Pete, but it appears better than Acetone. Looks like it's mostly naphtha (lighter fluid), another thing I'd be pretty cautious about around any sparks.
I have been using this along with the original DuPont Prep Sol for over 70 years. No fires even with acetylene torches being fired up around me. Nothing is risk free. Drop an engine on your foot and it might send you to the hospital. We still play with trains. YMMV
