Any hints on what I should use to create window glass in my 1/35 scale buildings?

I use transparent acetate to replicate windows on trucks, etc...
Is easy to work with and cheap, as it's quite easy to be find in the packaging coming with many product we all commonly buy . It's the transparent plastic sheet you find in many boxes. If it ha sgot scratches you easily remove them just dipping it in some Future...

You can purchase clear sheet styrene as one option.
Another option (in the US anyway) is the 'blister' packs that products are packaged in, such as kids toys.
Some food is packaged in clear material that can work too.

Here's another option: buy microscope slide covers from a science supply store. They really are glass and break just like glass breaks.

Just to add to the list. You could also use the clear transparencies usually sold in bookshops that are used for presentations involving a overhead projector. Just go down to any reasonable sized bookstore and ask for transparencies for overhead projectors.

Cheaper still are the plastic covers on batteries. The bigger sized batteries are better as you get more plastic. I find these good for making the glass covers on instrument dials.

Thanks for the tips, guys!

I used the liquid stuff from Micro-Mark. I liked the ripply effect like old glass has.
