I purchased some of that Mend-it worm glue a few months ago after ready mattlures post and seeing some other info on the web about it.  After getting the 1oz bottle for ~13 bucks i tried it and it really worked great.  I've actually gone to the trouble of tearing baits up just to see how well this stuff worked.  And the stuff worked just as advertised.  

Now a couple of months after trying this stuff i go out into the garage tonight to do some organization and notice i have some old plastics that "need fixin".  So i grab the bottle of Mendit and proceed to fix these baits.  But what i notice when i start to use the stuff is that it seems to have gotten thicker.  when i got it, it was pretty watery.  Now the stuff seems very gluey.  This stuff smells like nail polish remover.  So i wonder if maybe some of the fluid has evaporated.  Just a theory.

Has anyone else tried this stuff, and found the same problem?

I love it too. Same thing happened to me, But I never remembered to leave the cap on, so i figured I had it coming.

I love it too, I keep mine nicely capped so I haven't noticed the thickening.  I also find that it will form a thin layer over the opening and cap itself for me... (maybe when I stick the head into the bait it melts some plastic onto the top....)

I was actually ponder the idea of putting some nail polish remover in there to thin it out.  I'm no chemist but isn't that the same stuff that is in the MendIt?

Bring the glue to a "hobby shop" - the kind that deals with miniatures and trains and such. They usually have a wide selection of specialized glues and thinners. I'm sure they can help you. I wouldn't use the nail polish remover unless you are told to do so by the experts. Mixing chemicals can have dissasterous effects! Be careful.

Mend-it sayes on the bottle that it contains acetone.  You may be able to add a little acetone to the bottle to bring it back to normal.  More than likely the acetone portion has evaporated.  I wonder if straight acetone will weld two pieces of plastic together.   :  I think I will have to try this experiment at work next week where I have a can of acetone.

i went to the trouble of taking some nail polish remover and pouring some straight on a worm and it didn't seem to melt it any.  So i wonder if the acetone in nail poish remover has been diluted down.  On the ingredients of the nail polish remover it says it contains water.  So i'm guessing it cuts the acetone and makes it less effective on plastics.  I would guess that straight acetone from the HD would probably work.  

Tpayne, let me know how the straight acetone works after you try.

Absolutely the best for on the water soft plastic repairs.
