You can no longer buy Comastic due to H&S issues, dont paint your deck or gunnels in blacking you will regret it. I use Epifanes Multiforte
Fast drying, semi gloss, durable paint suitable for decks, walkways and roofs. Provides excellent protection for high traffic areas.
The added acrylic copolymer element gives this paint excellent adhesion to almost any surface.
Use on wood, steel and aluminium, inside and outside of above the water line, in combination with the corresponding primers.
For increased gloss level: add 10% Epifanes Clear Gloss Varnish.
Tough, durable semi-gloss finish
Excellent surface adhesion
Easy maintenance
