Malcolm,

What epoxy and hardener were you using? This may not be related to the cloudy finish issue but you sure didn't have enough working time to recover. It sounds like you were using a very fast hardener if it set up in 2 hours. If you were using Raka (you mentioned using their cloth) I would use their very slow hardener to wet out fiberglass. This ensures that you have plenty of time to work slowly and delibertly.

Regards,

Jack
