I've heard Nitromors is no longer any good, apparently does very little on stubborn paint. DCM on the other hand - apparently nasty stuff and can corrode metal if what they say on the internet is true. Found that 3M does something called Tal-strip II which is meant to be super quick and works on pretty much anything, shame it's hard to get in the UK.

Thinking about inside vs outside I do have a bit of a green area outside of the house, so indeed with the weather getting better I can stick something in a bucket / cardboard box and leave it to work, then use double gloves / mask to clean off and get primed for painting. I'd like to get the old paint off as it's chipped in places and if I just repaint it will look sloppy.
