What do people think

What do people think of these water additives that you can put in the water system to stop a small leak!?
The reason I ask is.. Im living in Venna at the moment but am traveling back to Wales in the begining of April. But I seem to have some presure in my water system, Im not realy loseing water but lots of presure . Don't want to take it to Audi and get ripped off for a headgasket change as I know a man who can do it for half the price when I get home.
So what do people think! Will it be easy to clean out the system? is it bad for the car?

Radweld won't stop a head gasket leak and I personally, would absolutely, totally, NOT drive it from Vienna to South Wales if the head gasket was allowing cylinder pressure into the cooling system. You'll probably need a new engine, not a new gasket, if you try.

I repaired a leaking heater matrix on my car with Wynns version of the leak fixer stuff, lasted for a year untill the matrix was changed.
