I am about to start my cozy and I am wondering the best epoxy to use. I have seen EZ Poxy, MGS 335, MGS 285, but I am not sure which one I should use.

There is a comparison here but the 2006 prices are a little old.
And a Gary Hunter presentation here. Pay attention to what to use on fuel tanks and what he says about post cures.
I have not bought epoxy in a few years and have lost track of hazardous material shipping costs but I suggest you start with a postal scale and a spreadsheet for mixing, then you can easily switch epoxies any time. What I do is punch a hole in the cans, fill the cup with as much resin as I think I'll need and add hardener to bring the total up to the spreadsheet weight, then plug the can-holes with a machine screw when done and put them back in the hot-box. It is not quite as fast as a dedicated epoxy pump but still pretty fast and accurate. I don't trust the in-the-can-pumps.
I mostly used EZPoxy and 83 resin. I liked MGS but it started to give me an itch.
Have you joined the Cozybuilder's list? There is always some discussion of epoxies. Search the archives.

Thank you, I think I will try the mgs335 and go from there.
