Need to exercise caution here, some paint strippers contain dichloromethane! Now banned for use as a paint stripper in most EU countries, but not in others. Dichloromethane (DCM) does not burn and it’s a very aggressive solvent - not the sort of thing you want in your fuel tank!
I was almost entirely joking about people picking up a fuel additive at the hardware store. It is just funny walking the aisles after reading about Toluene and that era in F1 and seeing a metal can and it says Toluene on it just sitting there with the other paint strippers.
