Which gelcoat cleaners are best at combating waterline yellowing on boat hulls? Ben Meakins dons his rubber gloves and puts 10 products to the test
PRICE: £18.39/2lt (£9.20/lt)
Chine Shine, which is available in 2, 5 and 20lt containers, is brushed on to the surface, left for 10-15 minutes and rinsed with fresh water. It’s a thin gel, blue in colour, and it went a long way. The results upon rinsing were comparable to the best-performing products we tried. It’s also the cheapest per litre of the products on test.
