Use Silkenseal to Seal
Achiles are great boats but all hypalon is porous to stains etc. That is why you seal the surface. Silkenseal forms a "plastic skin" surface that stops this.ALthough IG pInk is a great all round cleaner if you use SEA GLOW (on a bright colored, grey or black boat) there is also UV p;rotection, brighter colors, protectiona against oxidation AND mildew.algae.Sorry I did not notice enquiries down here rather than in the gelcoat and plastics sectionThanksJim WillisPS my Tinker still looks great after 7 years on the davist inthe tropics kept up with these products.
