LE 1499 Monocal GP grease in 14.1oz cans. This is an extremely high performing US made grease that withstands severe conditions including exposure to water. It's used on oil rigs and was recommended by technical specialists in Glasgow. I've recently applied it to the cables on one of my towers and it is by far the best grease I have ever used for that. The minimum order was 40 cans, hence I have surplus to sell at £20 per can. 1-2 cans should be enough for a tower. Delivery to RSGB Convention only. Please text me on 07785 258385 and I will reserve it for you. Robert McHenry G3NSM
