Can you help to identify these frames, bikes or parts?

You don't really need gloves, you would need a hell of a lot, left on for a very long time to really do your skin any damage. I used to do furniture renovation when I was younger and spent hours covered in the stuff, never did me any harm. Goggles is probably a good idea though, although I never have.

car paint stripper nitromors is different to the one which you strip furniture varnish.

You can feel the "burn" in the air soon as you start applying it. Would not want to get any one me. Have you ever tried to get powder coat off in any other way? its nigh impossible, yet this stuff gets it off in seconds.

If any of this got in your eyes, which is very easy to do. It would dissolve them. (dependant on how much got it)

Also if your working with a lot of caustic soda, over long periods of time. It can increase the internal pressure of your eyes. Which on a healthy person would just cause discomfort, but in others vision damage. without even touching your eye!
