one more time: epoxy help

Well, yesterday I put the first coat of LS Supreme on the RX8+ I had just wrapped. I went out for a few hours, returned and stuck my finger into the mixing cup to see how hard it was. Still wet! Noooooo! It had a layer of the orange tinted hardener on top of the gelled solution in the cup. I must have goofed up even though I used the syringes, went to the wrong graduations, or just didn't mix well enough. It got pretty hot in the garage today and I left it turning all day so that helped it get to a tacky state, at least.
Does this stuff get old? It's not crystalized. I didn't expect this with u40. Will the second coat set off the tacky first coat, or will I just have hard epoxy over soft epoxy? Should I try to wipe it off with alcohol first? I would appreciate your suggestions, Greg Re: one more time: epoxy help

If it's gooey wipe it off and start over. If it's hard but just tacky a second GOOD coat
will fix it just fine. Raymond Adams Eventually, all things merge, and a river runs through it.. Re: one more time: epoxy help

The hardner will yellow over time with most all 2 part epoxy finishes.
Some will yellow more than others. I didnt have my set of TM long enough(LOL) to see just how much it yellows but others have posted pix that show little IF ANY yellowing.

Thanks, Raymond.
I was afraid to try wiping it off, but after your suggestion I went at it with a soft rag and denatured alcohol and it came off just fine. All the threads are clean on the surface. I will let it dry out tomorrow and coat it again. I have some new LS Supreme so I think I'll throw out the old stuff even though I am pretty sure it was operator error. The first rod I did, the Flexcoat didn't set up well and I went over it with another coat (it was high build) and I wasn't happy, it was lumpy. Haven't had any problems with LS supreme, even mixing 2 cc parts each, in the past several rods. Guess I got over confident! Greg Re: one more time: epoxy help

You MAY have added to the problem by using the denatured alcohol for the clean up. The solvent COULD affect what is going on down in the thread and the tunnel. I would put it in the sun and add a few hours to insure that you have given time for the solvent to escape, if it EVER will. If solvent is in the underlying coat it MAY mess with the cure of the top coat. If I did not really give a hoot I MIGHT consider applying a coat of color preserver over the thread before applying a top coat of finish to build a barrier. That Rx8 is one fine blank and if you have the time you MAY also consider rewrapping. If it is a mistake on your part you should be punished so you will remember the lesson - rewrapping would sure be appropriate punishment for just about any mistake made! Please note the WEASEL WORDS words in all caps. We can all fire bullets but the final decision on just how you want to turn out a rod is yours alone.

I don't think using the alcohol ADDED to the problem. Adding more epoxy may have. I will let it dry out before finishing. Rewrapping will certainly take care of it if it need be. Re: one more time: epoxy help

Greg, about five years ago I did ssomething very similar. I work out of 4 oz plastic bottles with Yorker caps. I fill the 4 oz bottles from 32 oz main storage bottles. I filled both of the "use" bottles with new hardner that had no color. I will guarantee you one thing - two portions of hardner mixed properly will not set up! When the stuff did not get hard in the application pan I finally figured out what happened. I had done two rods with the bad mix and I wiped them off with a rag and alcohol and applied a good finish mix over the top. The only thing that was securing the guides to the blank was the overlap on the end of the wrap. The guy brought the rods back to me and told me the guides were rotating on his brand new rod! My punishment was a mad customer, poor references and increased medication costs. Re: one more time: epoxy help

could you burnish it to move around the threads to make sure if there is any alc. under it will get out? Re: one more time: epoxy help

I think one day in a warm corner of the garage where the workbench is will evaporate the alcohol. I believe the hardener separated out from the mix by either using 3cc of hardener to 2cc of epoxy or just not stirring enough, so there was a film of hardener on top. After letting it dry I will check the threads and how well the guides are adhered before finishing the wraps again. At some point it is better to cut my losses and redo the wraps.
