About Us

We are G.U.K. Manufacturing operating out of Dover, Kent in England. Originally founded in the summer of 2001 G.U.K. Manufacturing began its research and development into solutions to stern gear fouling. Five years later we were proud to release Propshield Antifouling Grease onto the world market.

Mission Statement & Commitment to our Customers

We would like to bring the benefits of this product to fellow boat owners, commercial operators and shipping fleets who constantly fight against barnacle attraction, hard growth, electrolysis and oxidisation. We will continue to research and develop other products that we will bring to the market in the future to enhance cruising pleasure and commercial profits; In doing so we plan to keep this and other products that follow as natural as possible to protect the environment for future generations. We do not see the need to adopt chemicals that are derived from oil and will endeavour not to use products that are not environmentally friendly or are not available from renewable resources.

On behalf of everyone at and G.U.K. Manufacturing I hope that this website and our product will make your boating and shipping lives easier, more enjoyable and less costly for many years to come.

Yours faithfully,
Terry Storey
Co-owner & founder of G.U.K. Manufacturing
