Pram Tender build Phase 2

Well, it's coming together! After ordering $180 worth of resin, hardener and tape (including shipping) from www.jgreer.com, I spent some time reading up on how to fiberglass something. Keep in mind I had never so much as mixed up resin of any sort so I wanted to gather any information that would help me not screw this up too badly. The resin came with specific instructions which I followed. The gist of it is make sure the resin and hardener are mixed in the correct ratio and thoroughly. I will say I used cabosil as the thickening agent and it was messy and nasty--wood flour next time. Per instructions, I made a fillet of epoxy in all of the interior corners then laid fiberglass tape in the corners and used a brush and some un-thickened epoxy to "wet out" the tape. Three inch wide tape was called for in the plans but the supplier only sold 2 or 4 inch tape. I hope the 2 inch will be okay. The process went fairly quickly and it was far more trouble to pull out the stitching afterwards then glass the corners on either the inside or outside of the boat. I will say that all sharp corners should at least be slightly rounded as tape does not like square edges and doesn't always adhere to them. After I cut out the stitching (zip ties), I spent a short time trimming up the outside edges and sanding them with my electric sander. I then filled the outside just like the inside and taped all of the corners as well. Plan on 6 hours to complete the inside and outside corners. At this point, I am waiting for more resin, hardener and 6 oz cloth to show up, so I can complete the bottom of the boat. Below are two photos of the progress.
