What is Flex Paste used for?
It's a flexible, non-cracking modeling paste for model railroad scenery — priming foam for roads, creating water features over Plaster Cloth, blending transitions, and building up snow effects with Soft Flake Snow.

Does it crack when it dries?
No. Flex Paste is specifically formulated to stay flexible and resist cracking, and it will not shrink as it dries — unlike standard plasters.

Is it waterproof?
Yes. Once cured, Flex Paste forms a durable, waterproof surface, making it ideal for modeling water features.

What scales does this work for?
All scales — HO, N, O, G, and Z. Scenery paste is universal because you apply it to suit the size of your terrain feature.
