Sanding a deck for flow coat?
I am planning to flow coat the deck later this year when the weather warms up. The purposes of this work is to tidy up the deck which will have had a new jockey console attached to it (glassed in) and a glassed in Deck matrix to allow for removal jockey pods. The deck is embossed with small squares circa 1mm each (see attached photo).
1) Do I need to sand the deck smooth to get a good finish with no slip flow coat?
2) I have found that the use of an orbital sander gives a very good finish but is very very slow. The grinder is very fast but the deck needs sanding after it to level it up a bit.
You advice on this stage of my project please..
