A Question Of Chemistry

[catsrcool]

I am using model paints thinned with 2K Automotive thinners.
I need to buy some small disposable mixing cups that will not react with the solvents.
It was suggested that I buy ones made from HTPE. Here is its chemical resistance chart:

And the solvent I am using:

So please can tell someone tell me if the HTPE will resist the solvent?

Are your paints stable with metal, if so how about a cupcake baking tin 12 deep holes and can be cleaned and re- used. I used them as palettes when using glass and ceramic paints.
