 In South Africa, the holes in two partially sunken ships were repaired with Pratley Putty, which can also cure under water.In 2019 Pratley Putty became a part of the SA Mint's "South African inventions" commemorative coin series, commemorating its use in space.Today the company also produces a fast-curing version of Pratley Putty called Pratley Quickset® Putty as well as a metallic-looking version called Pratley Steel Putty.
