Epoxy Topcoat I Use

Yellowing happens in very subtle stages. Four months probably isn't enough time to judge the propensity towards yellowing. Yellowing can take a while to even notice because you normally store the baits out of the light., Therefore, when you say 4 months that may mean as little as four hours in the direct sunlight.
Over the years we've had a lot of discussions about yellowing. (If I had a dollar for everyone here who swore that D2T did not yellow, I'd be rich. )
From my view, yellowing is an undesirable trait because it distorts all the colors, not just the white or the lighter ones. If you're going to go to the trouble to mix the colors you want only to have them yellow later...well, I don't want that if I can avoid it.
EX-74 is a clearcoat made by envirotex with UV protectors in it and I've had almost no color shifting using the stuff.
You also have to remember that yellowing is only one of the problems you have from direct sunlight. Fading of some of pigments is another. The more brilliant colors tend to fade the most from direct sun. UV protection is important in that respect also.
Much of what we do as builders is a matter of esthetics. That a bait will still catch fish doesn't mean that the yellowing hasn't defeated the purpose of putting all that time into one bait.
Just my 2 cents.

I understand what you're saying. 4 months for these baits means probably 60 hours in the sun being casted or trolled at the surface. My area has a daily UV index of 10. They also hang in my garage which has windows so although not in direct sunlight the garage is lit by sunlight. Most of what I have seen threads about here are topcoats without any UV stabilization or with various other problems that I don't have. I'm just sharing what I've found to work well. When I find something better I'll be happy to move on.

If you take one of your baits...maybe one your not going to use...and hang it outside in direct sunlight and leave it there for a few weeks...you can get a better idea of what is going to happen to it...That should be more sunlight than it will see while your fishing it......And if you want to use something that you don't have to worry about ....use automotive clear coat...just make sure your setup for it....just my

Yeah I know, you said the same thing was said about 15 posts ago. I'm not the one concerned about it's UV rating, it seems to be others here. It's curious why everyone is so concerned about this topcoat not being UV stabilized where most others proclaimed to be good here are also not UV stabilized. Most don't say one way or the other which means that they aren't. This comany said it will yellow over time in respect to using it as a concrete sealer where it's in the sun everyday, all day. I could hang a bait outside for a month or so but it wouldn't matter because this seems to be the topic now, not a good topcoat without the problems most others are having. I'll revive this thread in a few years, maybe.

Have you used EX-74? I went over to their site and in reading the MSDS it was using statement like use in a well ventilated area and what to do if breathing stopped. I think I'll pass on that one.
HEALTH HAZARD WARNING STATEMENTS:
USE ONLY IN ADEQUATE VENTILATED AREAS. AVOID BREATHING VAPORS OR MIST. SKIN SENSITIZER. WILL CAUSE EYE AND
MUCOUS MEMBRANE IRRITATION. WASH WITH SOAP AND WATER AFTER USE.
INHALATION: Inhalation of high concentrations of vapors may cause irritation to the respiratory tract. May cause
Central Nervous System (CNS) depression. Prolonged or repeated exposure of high concentrations of
vapor may asthma or other allergic responses.

That is pretty much the same warning that you see on d2t,which is what almost everyone uses to glue in lips, screw eyes, etc. I use both d2t and ex74 with ventilation.
I was simply offering my experience and opinion on the idea of spending time and money to build a lure only to topcoat it with a product whose label tells you that it's going to yellow.
As others have told you, if you're happy with the stuff, then by all means go for it.

Sorry just trying to help out........................

No problem, I'm sorry about my tone. I did take a plug and hang it outside yesterday to put it through a UV nightmare. We have a UV rating of 10 everday here so it shouldn't take long to see what is going to happen. I put a piece of tape over 1 area to get an area that shouldn't change. I would guess a week in direct sunlight, 12-14 hours a day without any water to filter the rays should equal close to a years use. I'll check it every week or so and if it is slow yellowing I may give it a month.
