It's brilliant for stripping Farish coaches, prior to using vinyls or whatever - leave for 24 hours and the paint just falls off leaving a perfectly clear shell. I was so impressed I did too many. Sure I can think of something to do with the extras!  :doh:

Thanks, everyone; I think I've got it now - IPA's OK on unpainted wheels or for removing unwanted paint, but don't drink it as it's not as good as ethyl alcohol .

I used a small eye dropper with a rubber bulb to fill my Tomix track cleaner with IPA.  After a few years it had eaten through the bulb.  At least I assume that's what it was.

Accidentally  spilt a drop or two on the roof of a siphon G which I only noticed next day but .......it actually looks quite authentic as weathering so decided to leave it.

Correct me if I am wrong but I think it has some connection with Acetone, which would explain why it may attack some plastic especially abs or polystyrene.

I don't think IPA has any connection with acetone and it doesn't have much effect on most plastics. I did a previous post on this _ can't find the link. However IPA attacks paint.

You can make IPA by hydrogenating Acetone, that is pretty much the only connection other than being organic.

I got a drop of IPA on the tender of a loco, noticed straight away and managed to cure most of the damage later with polishing compound but it was pretty nerve wracking.  I have always been very careful with it but accidents do happen, especially if you're not concentrating fully.

Where it states that it can damage ABS! 

It wont attack polypropylene, a lot of solvents don't even Acetone, I can confirm this as I use quite a lot of the stuff which is sold to me in 5ltr polypropelene cans!

I buy it in 5l cans as well and use it to get tyres for RC racing cars off the rims once worn out. They are glued on with CA and the acetone softens it very effectively leaving the wheel rims ready for a new set of tyres.
