Paint Stripper Alternative

I'm in the middle of stripping the paint off the frame of the Townmate, but now run out of Nitromores paint stripper, i have used it in the past but then it seemed more effective, now it doesn't wrinkle and bubble up as before. Have they weakened it because of some E.U directive? can anyone suggest a stronger stripper that they have used, before i buy another can of useless Nitromores?

its old paint well cured so any paint stripper will struggle battery acid but don't get it on your clothes

The last paint i stripped was about 5 years ago on a 1978 Suzuki gt380 and it worked fine on that, they have definatly dumbed it down.

not up to Yamaha t 80 paint standards ,, that's why
