So, I learned today that liquid poly, used for styrene builds, disintegrates Woodland Scenics foam sheets. This unpleasant discovery came about as I was sticking styrene detailing to a foam sheet base while scratch building the main platform for my Bayswater Station layout. I applied some liquid poly to the foam sheet, reached to grab the styrene strip that was to be glued to the sheet and by the time I went to apply it, found a sizable crater right where I was planning on attaching the styrene.

Good thing I have some foam putty which I can use to repair the foam sheet. And some PVA glue that I can use instead ...

A good warning.

The best way to glue anything to white polystyrene is to use pva.

I did the very same thing yesterday! To polystyrene risers for an incline. Expensive things to be melting.
I've now got some UHU expanded polystyrene glue which is just the thing.

Damned meteorite strikes are a PITA
