Filling, Fairing and Non-skid
   A tedious and laborious job made much easier by rolling the hull over and working on horizontal surfaces at a convenient height. I won't go into details of fairing here, so I'll just include a few tips. A little dish washing liquid added to water can prevent wet and dry paper clogging when sanding epoxy. I use Q Cells as a filler for fairing above the waterline. It's low in strength compared to Cabosil but easy to sand. Adding a little Cabosil to the Q cell mix stops it slumping on vertical surfaces.

 The hull is faired and the hi build sanded and it's looking good but there's another steps well worth doing. Apply a guide coat of any dark coloured paint you have lying around and leave it to dry. If you use water based paint leave it plenty of time to harden.

 Then sand it off with fine paper. Any small voids that require further fairing will be obvious as the dark guide coat will remain in these spots.

   Apply non skid.
   It's important to work wet on wet, you can't sand between coats as the surface is deliberately rough. Mask off the edges of the non skid area. Apply a liberal coat of epoxy, sprinkle the non skid on and when the resin is still just tacky use your compressor to blow the loose non skid off.
   Roll another coat of epoxy over the area and when this tacks off, roll on a coat of 2 pack polyurethane. Remove the masking tape.
   Out with the spray gun. Note that each hull side is painted while it's laid over, much easier for the amateur painter. Mask off areas you don't want any overspray on. After a day or 2 roll the hull onto the other side and spray away after masking the previously painted surfaces.
   Antifouled and ready to go..
