The BR website states that the uncoated R-3318 foam is rated for 800’ depth while the coated foam is rated at 1600’ depth. However, as far as I can tell, it doesn’t specify which product is being sold. Does anyone know?

Cheers,

Hi @tylerssims,

The foam sold is uncoated.

I would reach out to the manufacturer, [General Plastics](https://www.generalplastics.com/products/r-3300). Their site suggests they may be able to provide it coated upon request.

E-mail [Geoff\_veld@generalplastics.com](mailto:Geoff_veld@generalplastics.com) spoke to him earlier in the week about manufacturing foam, very helpful and informative chap.
