Plastic "crazing"

When it sniffs enough fumes?

I'm sure that helped him Ron!

It's when CA, Plastic model, or other types of glue cure they give off fumes from the reaction (to air). These fumes will "craze" or "frost" clear plastic as it etches or eats into the surface. It will also show on colored plastic if enought glue is present. You can minimize it by providing a draft for ventilation, but on clear it's best to use white glue (Elmers) or Future to attach it.

Hope that's more help than Ron's answer, though his was technically correct I suppose

Solvents found in laquer paints and associated thinners will also craze bare styrene. That's why it's important to have the model appropriately primed before laying down a laquer topcoat. Evidently, crazing first described fine cracks that appeared in the glazing of pottery. I guess it would be logical to assume that a similarity of sorts exists between the cracks in glazing, and the change in the texture of styrene as it is "attacked" by non-compatible solvent-based materials.

lol!

Keep it up and you will see some Ron crazing!
