I know old flex coat has been discussed on hear before but can't seem to find the threads to answer my specific question.

I've got some old ( 6 years ?) flex coat high build that has never been opened. One of the bottles is yellowed to about the color of honey. They were in a POD being stored when I moved but don't know if they froze or not. Should I just salvage the syringes and toss it or is it still good, just discolored?

They should still be OK, especially as they are still sealed. The Hardener is the one that should be yellowed and it wont effect it's curing.

Ed I have used it after 15 years and it was just fine. The gardner does yellow very slightly but you will be fine

Ed,
You can use it and it will likely be fine.
But I would at least rather start with a clear - non yellowed finish so if it were mine - I would pitch it and get fresh finish.

If you check out some of the new finishes, you find that some of them seem to have fewer issues with yellowing.

I am with Roger I have not used it cause it yellowed rather fast Don't know about any of there new stuff but it has many that use it Flex Coat is real nice Then again I have used many brands and found them all to be nice. Depends on what you are looking for

It could be used for tinting and making colored winding checks ??

Do you think the new finishes have advantages over this "old Flex Coat" as far as yellowing? I would like Mr. Kirkman and other senior members with lots of experience with the high build version of Flex Coat, to chime in with opinions on yellowing. It's my understanding all epoxy finishes yellow over time. Are we talking about looking yellow right away? The reason I'm asking is because I bought some "bargain" Flex Coat at the expo, and the hardener looks really yellow. I built a fly rod for a family member with it, and it seemed very clear, not at all yellow. However, this fly rod was built on a black blank with red thread. Maybe it would be more noticeable on lighter color thread or blank? I'm only asking because I have 5 more rods to build, one which is going to be surf/pier rod with some decorative thread(tiger wrap,ect.) and I don't want to ruin all that work with sub-par epoxy. Sorry if I hijacked this thread.

All epoxies yellow over time. Nothing has changed.

Keep in mind when you look at the bottle, you're looking through a very thick layer of epoxy. What you put on a wrap is far, far thinner.

As someone mentioned a while back - beer in the bottle is a bit yellow/amber, but pour it out in a puddle and it's clear as water.
