I coated the bottom of my aluminum boat with Gluvit and it's hard as a rock now.

Do I need to lightly sand it before painting with Duralux aluminum boat green?

Thanks

Yes you do. Some epoxy mixes may also emit an 'amine blush' that needs to be removed before top-coating with another product. Some require a wash with a cleaner and some a wash with a solvent, but I don't use Gluvit so can't advise here.

But I'd follow Gluvit's directions in this regard ...

Damn I'm good :wink: ... just had to look it up myself! Here's Gluvit's info:

To overcoat Gluvit after cure, wash the surface with warm soapy water or a dilute vinegar solution and a fine abrasive pad, or wet sand, then dry with clean towels or cloth. Frost-sand surface with 80-100 grit sand paper to remove any gloss. Gluvit can be overcoated with any marine paint or other coating compatible with epoxies.

Polyester resins, like gel-coat, do not adhere well to epoxy material.

All Gluvit containers are slack-filled (they are not full.) Materials are packaged in our facility by weight. This leaves enough room for a power mixer to blend the resin and hardener entirely.
