Thread: bote cote epoxy troubles - filling biggish holes and remain clear.

Even the best UV stablised clear finishes will have a shorter life and far less resistance to sunlight than a similar opaque finish.

Yes, this is with all epoxies, not just the pour-ons. For external applications, you need to overcoat with a UV resistant coating such as West's 207.

The cloudiness of epoxies come mostly from bubbles formed in the hardener/resin mix. Of course fillers, inhibitors and modifiers in the mixture also affect the cloudiness of the cured product. If West 207 is poured more then a 9 mm thick it will be quite cloudy.
