Goof Off Graffiti remover hasn't been chemically weakened so it will still chem.burn your skin vs BS like Citri Strip that basically will just give your original paint a nice barely thinned down scent. I'll bet you 15 mins of Goof Off Graffiti remover will do a lot more damage to both an over painted frame & original paint than any eco friendly "safe" strippers would begin to do. Hell double it 30 mins & If I'm wrong then I'll admit it. I'd rather spend
$9-12 for a tall can vs having to BS recoat, scrub, and wait to find out I wasted time + money. Not arguing and saying you're wrong or anything but I know what I have used, experience, and my personal preferences.
