Once I had a finished foam core ready, it was onto the fiberglassing. There were some dents and marks in the foam from knocks during the making process but I decided to go ahead and fibreglass the board anyway and fix these later because I didn’t have any expanding foam.https://compositecorner.wordpress.com/tag/how-to-cut-lap/

I will be using the cut lap method for the rails of my board. This is where you use tape to mask off the underside of the board and then trim the fibreglass along this line. Here I am masking off the top deck of the board except for a roughly 10 cm area all around the rails so that I can have an overlap between the top and bottom layers of fibreglass. I also had to make small incisions every so often so that the cloth would wrap around nicely. They had to be closer together and more frequent on the areas of the board with tighter curves like the nose and tail. Next, I laid the cloth out, Mixed up my two-part epoxy resin and poured it on the board. I found it was useful to have a ‘squeegee like’  tool to direct the resin (I used a bit of plastic sheet) and to pour the resin in sections to ensure I didn’t run out. I found it was important to make sure the overhangs were fully saturated with resin before trying to stick them round, otherwise they didn’t stick nicely.
