Hey Rookie thats exactly what I do to seal my baits, I cut it way back depending on the type of wood more so than any other reason, hard wood like white oak or Maple I get the stuff to run like water, it soaks in and makes a rock hard surface, I do 2 3 coats sanding between, for Ceder it can be a touch syrupy, I highly recommend it, I only use denatured Alc for cutting, it works great so I'll stay with that, the reason I cut it for coating a lure is most Muskie baits have allot of surface area, some of my big baits the epoxy would be set up before I got it covered, more importantly it makes application allot smoother off the brush, cutting add's a bit more to the window, but not much you still gotta MOVE, lol, hope this helps.

Muskiefool - I kinda know what you mean with the devcon setting up before you completely cover the lure. I don't make muskie lures but I have been making lures that are over 4". I'm using the 30 min. devcon but after mixing for a few minutes and applying to the lure it starts to set within about 5 minutes! how much denatured alcohol, iso alcohol, etc. is recommended to mix a batch of devcon for a 4" lure?

About 1 to 1-1/2 teaspoons per package, so I'm guessing about 10-15% roughly, I've done it with more lets say 20-25% and that works too, I would say it's not a perfect science now for me, I was getting very particular with my mixing but I sorta use the Julia Childes method now, LOL, the main thing is to mix the epoxy first incorporating it as fast as possible then add the best Denatured Alc you can find, mixing in a clear glass with a clear plastic spoon so you can see when it's clear of the oil and water look, and remember this is very flammable. Good Luck

What Dean says is applicable...you may be better served by a different product that you don't have to modify.
While extending working time of epoxy with iso (maybe denatured)regardless of the method of mixing, etc. I feel it is best to add in small amounts, stir, check consistency, add, etc. until it gets what you want. A "small" amount can be as little as a single drop. Depends on how much D2T you have mixed and how much it has hardened.
You can extend actual working time of Devcon close to or maybe beyond the stated time on the package by using iso. I think the working time they claim doesn't apply for our use of the product, but that depends on temperature among other things.
To those who asked why I might thin, I refer back to my original answer.

thanks guys for the excellent responses and the sound advice.
as for etex lite, I've tried it but have used d2t much more and am comfortable with it and the way it holds up. i just wanted to fine tune my application of the product.

I didn't have much luck with the lite I'm going to try EX-74 possibly, anyone have any experience's with that stuff it sounds good, I know 1 guy that likes it.
