Low compression

I have a 94 with 2.5l. It has low compression in #2 & #3 cyls. It only has 86000 miles on it none of which are hard driven miles. I've heard of a product you can use to unstick piston rings for a better seal, pls someone let me in on the secret of this mystery fluid. Plus, how long will this work. I will be doing a complete overhaul of the engine in the future, but for now the timing and the funds are not available. Any help will be greatly appreciated.
Thanks

Hmmm, there are some chemicals you can try in your local store. I think one is Restore...comes in a silver can, supposed to be pretty good. But the only way to really restore your compression is by replacing the rings and cleaning the cylinders/pistons. Remember, its not always your rings fault for low compression

One possibility is that the head gasket is blown between cylinders 2 & 3 causing poosr compression on both cyls.

Any chance you might share your secrets?

All in all, i'm not much of a believer in additives, except for maybe fuel-injector cleaner.
