Not sure what happened but this is the scenario. I was building 4 rods at a time and started with finish on all of them. But I ran out of the that finish on the last two rods that already had a coat of finish on it and had dried after 12 hours on the dryer. I then put Threadmaster lite as the final coat on top of the dried other finish. The finish looked ok when I applied it but soon after it started to develop small pimples on the surface and would not cure. It remained sticky and gooey and would not cure. Was this a reaction from using the two epoxies? Are they not compatible to a degree that they interact with one another? Unfortunately, I had to strip the two rods and start rewrapping again. I will never do that again! LOL

Sounds to me like improper ratios or not mixed well enough.

I noted the name of the product you used before it got edited. To the best of my knowledge that is a repackaged product and it could have been contaminated when the seller poured it from one bottle to the other. No way to tell.But I can't really see two rod finish epoxies reacting with one another. I've put different epoxies over each other and never run into what you state above. I would look at something else as the cause of the problem.

I use the syringes for measuring the epoxies and I continued to use the Threadmaster on the rods after re-wrapping and it is curing properly. The the other finish was used on a number of rods until I ran out and it cured properly as well. All that I can come up with is that they have a compatibility issue between the two. Perhaps had the epoxy completely cured... ie longer period, this would not have happened? Anyways, I will never do this again unless the epoxy is completely cured. I mix for three minutes and I did change to new syringes when I changed epoxy. If I missed the ratio a bit, then it would be just a problem of tackiness which can be fixed with an additional coat. But this was a sticky mess with blotching and surface pimples that could not be fixed with an additional coat. So, I chose to re-wrap and not mess further with it.

I think Scott is correct on this I have done some nasty things but when that happened to me It was a improper mix

I must admit that working on 4 rods at a time, things do get mixed up a bit. Seems that every one says that different brands of epoxies would not react adversely against one another. In my haste, I may have had some air bubbles in one of the syringes that may have caused a bad mix but when this has happened in the past, I was able to re-coat and fix the problem. But, why did I have this blotching and surface pimples this time? Can this be caused by improper mixing and to what degree? Thanks all for your answers.

Do the pimples look like craters or bubbles? Is it possible you mixed two syringes of the same component (resin or hardener)? Can you post a photo?

It was more like craters. The rods have since been re-wrapped so no pictures. I don't want unpleasant reminders... lol
I am very confident that my methods preclude mixing two syringes of the same component.

Mel,
I know that you have already stripped, cleaned, rewrapped and refinished your rod.

But, to me, craters sound like some sort of contamination, like a silicone or something similar. Maybe a touch of oil from something or some where, a bit of silicone from some thread or similar or??

Be safe
