Ok G4 is a Cement Sealant that is put on Cement to seal from Limescale and Chemicals in Cement Ponds or Water Courses that can be detrimental to Fish,Frogs or Newts. Available in Clear or Black. It is very tricky to clean off Brushes so I tend to use Sacrificial Pound Shop Ones on each coat, also best to wear latex Gloves under thin old Gardening Gloves when applying. Tends to look like Oil if any gets into a Wet Pond then congeales to clog up pumps so important to apply to a Dry Surface and let dry off. Last time I got a 1kg Tin it was about £30 but does go a long way even with the recommended 3 coats. I get it from a specialist Water Garden Etsblishment. Oh does no damage to Butyle Liner in fact any cement on the liner you can seal the Joint with it as I have done on my Rill and around the Water Mill where the Water runs to get into the Small River. Hope that helps Jimmy.Jon, very nice, you mention G4 could you expand please
You need a slomo on it, JonDecided this morning after posting about the Mill and Rill to make a new Wheel. Unashamedly copied Ge_riks methods to make a new one out of Plasticard as he has. I have put a couple of 00 Brass Bearings for the Wheel to trundle around on some 1/8th KS Tube and am pleased to report that it works just fine. First pic shows the Wheel drying in the sun. Is have sprayed some Green to represent the Moss that would be present on a Wood Wheel.

This picture shows the Drop of Water in the Tank when the pump is running, some 2-3 inches from what is a pretty large Tank.

Next pic shows the Narrow Water Course that returns the Water to the Tank. In my world this is the Selktal River.

Another pic of the River showing the Old Mill Wheel unceremoniously dumped in the River with some old Wagon Chassis, sort of thing used to happen in the bad old days of East Germany when under Communist Control.
