Mer Rainaway

Great price helps make the Mer our pick of the conventional repellents, as its performance fell away only at the finish of the test.

You need two applications, but it buffed easily and the big 500ml bottle would last years. Starred early on – we struggled to fill its section with water – and only at the end did its resistance to the hose begin to slow down.
