Has anyone tried a liquid or sprayable sanding sealer like Minwax?

Two main ways to do it... A thick coating that creates an internal shell - like a plasti-dip or more industrial polyurethane or epoxy. The other is a low viscous sealer that will soak into the part and seal the porosity - like a polyurethane or cyanoacrylate.

A few other notes. Sealers don't work well once the part has already been exposed to the liquid and started to leak. Also, you want to run very dense parts. Machine settings will definitely impact final part characteristics and properties.

Hi all,

What is the best way to seal a hollow Duraform GF part to hold liquid with no leaks? Please advise.

Thank you,
