I use it for both fresh and saltwater fly tying in head and body building. IMO (and in the opinion of all the tiers I know) it's easier and safer to use than epoxy and yields a better finished product.

As for use in household repairs bear in mind that all the substance has to be exposed to UV in order to cure. I use Loon Clear Fly finish which comes in several consistencies but the thickest one suits my purposes. UV flashlights can be expensive but I got one from Amazon for 6-7 bucks and it seems to work just fine though I hear some of the more expensive ones give a faster cure. Unless I'm in a hurry I give my flies a quick exposure to the light and them set then out in the sunshine for an hour or so which makes them very hard.

Loon resin seems to leave a slightly tacky residue but that can be removed with a quick wipe of isopropyl alcohol after your work is fully cured.

One more tip: When ready to cure hit your project with 5 seconds of UV and let it set for 15 seconds before final cure which takes 30-40 seconds depending on the amount of product you've used.
