well sounds better than prochems, i like to do my best to put down the right amount so it works properly, always an element of guess work though, i charge £30 protect a lounge, i would'nt want to raise that i think thats fair, i want a cheaper protector, to raise profit marging.
i saw a london c/c website other day advertising £10 a room protection, lol how do they manage that! ?
must use a special one like water.
