Dry mounting press sponge pad alternatives
I've been lucky to score a used Seal Masterpiece dry mounting press which I'll be using to flatten and mount prints. Unfortunately it came without the sponge/foram/rubber pad on the bottom. Located in Germany, I have been unable to locate a source from which I can order such a pad. I would import it myself from the States, but shipping costs are just insane. So I thought of looking for alternatives first.
Did you use some other material except the original sponge pad successfully? If so what's your solution? I gather heat resistant and kind-of-soft but not too soft good - but that's very subjective. Maybe there's an alternative easy to source material I can use, like a certain type foamboard, or anti-splip rubber mats, camping mats, etc.?
