Any of you use an airbrush for painting?
I was looking at buying another Preval cartridge to touch up in the engine bay but starting thinking maybe it would be smarter to buy a small sprayer.
I've still got some old acrylic laquer that was used in the engine bay so it should match. Just want to go around the master cyl and bulkhead connector. Top of inner fender too.
I never thought of that. Using an airbrush for touch up
