2nd coat of etex.

I don't use e tex but 72
Is good for my epoxy too. Just be careful with the pad and alcohol along corners, edges, and ends. The alcohol will take the paint off. Done that many times. Then you will be pissed.

I also go with the max of 72...... scuff with scotch bright and wipe with a new tack cloth...no alcohol..wear rubber gloves or wash your hands thououghly with Boraxo so the oils on your hands don't transfer
