All: does anyone know of a safe way to remove aerosol spray that is on top of good original paint? The Standard model K I recently acquired (see my other thread) has had the fork and chain guard sprayed lightly with black aerosol, and I can remove a lot of it with my fingernails (exposing the original pinstriping etc).....however I'd like to get it off more quickly and with less wear on the thumbs....
Goof off and a green plastic brillo-type pad. OR you can try laquer thinner, but becareful because this can also soften the finnish beneath. Try it in an inconspicuous spot to see. If the old finish is well cured enamel it may hold up to this treatment, while the newer softer paint will wipe off
You might want to try detailer's clay. It's a synthetic compound that is specifically made to remove contamination from paint. Body shops use it to remove overspray from painted surfaces. Automobile detailers use it to remove embedded dirt in the paint on cars.
You need to use some soapy water as a lubricant and just slide the clay over the surface. The clay actually shears of the contamination and holds on to the grit. It's very gentle and leaves a silky smooth surface.
