Now that Nitromorse has lost it’s kick, what can people recommend and where to get it?

Tried my local car paint supplier and they offer 5l for £30, don’t think I’ll need 5 litres so want something smaller / cheaper?

I have read that aircraft paint stripper is good but don’t know of a shop that sells aircraft parts around here!!

Dichloromethane is being phased out of use in Europe for (very good) health and safety reasons.

I think you’ll struggle to find a retail product that contains it soon.
The new nitromors does work but takes a little longer. It now uses Benzyl alcohol IIRC which is not as good a solvent but equally not a carcinogen.
