I have a CVA Apex with the black rubbery finished stock that is becoming sticky. Not sure what to do to fix it. Also, I have another forearm for the Apex that has been camo dipped. Its so sticky that you won't want to hold it. I can tell you that acetone is not what you want to use on the hydro-dipped camo forearm. Is there a fix for this? Maybe a paint job?

Acetone? Yikes. That schit'll about melt glass no doubt its made the stock sticky. I think you're hooped I'm afraid short of sanding away to see if its not affected deeper down?

Call the manufacturer/hydrodipper.
I'm sure they've seen that before.

Hope it works out without big cost.
