Board Building Project - HD Creeper 48 - Stage 8 - Clear Coat, Pads & Non-skid

Time for the final clear coat, sanding and non-skid.  I will keep a matt finish which shows the weave when wet - just like the finish on fins.  My non-skid was late night inspirado and I already don't like the waistcoat looking front - this will change down the track.  Also had a bit of trouble with the non-skid fisheyeing over to 1200 finish underneath - another experience for the memory bank.  This will be the last clear finished board I do, opaque sanding coats are so much quicker to finish.

 Clear coat, none under the pads to save weight.

Board Building Project - HD Creeper 48 - Stage 6 & 7 - Hull & Deck Lamination

Deck is bagged(200g Twill carbon, 130g plain glass + patches) and initial sanding is almost finished. Next up is to fill a few low spots I should have filled before glassing but couldn't be stuffed, then a finishing coat for polishing.

I glassed(2 x 130g plain glass + patches) the hull old school(not bagged) and everything was sweet until some gassing of the dcell combined with some crimped glass to form a few bubbles.  Yet more repair work.  The newer surfboard glass(130g) seems to use smaller glass bundles(and have larger openings in the weave) which leaves more resin on the layup table.  I think the layup might have been on the dry side as a result which doesn't help.  I probably should have glassed the hull on the board then feathering the 2 layers around the rail would have been easier.

There are a few tricks I tried for the hidden (under carbon) inserts which worked well.
