Hi all,


I've stripped the paint off an old steel frame using chemicals (nitromors) and although this has taken off 95% of the paint, I've been left with a thin layer of... something. I have no idea what it is but it has come up in some places but not others leaving an uneven finish on the frame.


I first thought I messed up the frame by corroding it with the chemicals or something. But nitromors seems to be a popular choice for this sort of thing and I haven't used too much.

I'm thinking it could be the remains of the primer, or maybe an anti rust paint of some sort.. but it refuses to budge. No amount of paint stripper, sanding, or even a wire brush is removing it. Any ideas what it might be? The frame is mid eighties and has never been stripped down so this paint as been on it for years... I'll try and get a picture up shortly.


Has anyone come across this sort of thing before?!!


Thanks


Stephen
