Has anybody tried plastering over rigid foam? 

Owens Corning Pink.  They recommend plaster cloth or thinned plaster painted on. but this will obscure detail of sculpted "rock".

Should I be worried about not having any fire retardant on top of my rigid foam layout?  I am thinking about gluing 1 inch pink rigid insulation on top of my 4x8 plywood table to allow me to carve a stream bed and other topographical features, but I have heard that this foam could be a fire hazard.

Please advise,

Thanks everyone!  and yes 15" radius...

To clarify, that is HO Atlas code 100 curves.

Does anyone have thoughts about using 15" in diameter curves?  Are 18" better?

Thanks

Thanks for your input.

2 quick questions:

Did you use a chemical stripper?

Did you find instructions on taking the engine apart or is it just trial and error sort of stuff?

Thanks so much!

Has anyone painted a Hawthorne train and been satisfied with he results?

Has anyone painted a Hawthorne engine and been satisfied with how it turned out?

Thanks for the quick response!

Does the Hawthorne engine have the see-through clearance under the boiler?

Thanks very much!

Are there any significant differences between the above engines?
