How To Fiberglass Over Plywood

In this video I am using laminating poly resin, 1.5 oz csm and 1708 bi-axial glass. In order to ensure a good bond onto the plywood it is essential to pre-coat the surface with resin! Not doing so will almost certainly result in a dry layup and de-lamination 🙁 Not good… In total, I used 12oz of resin to pre-coat the surface and layup all the glass shown in the demo. The fin roller I used to establish the radius on the fillet is 1/2″…

Installing New Fixed Portlights

In this video I mount some new fixed portlights using 3M VHB tape. VHB stands for Very High Bond, and it does exactly what it says it does! When installing polycarbonate or acrylic panels / portlights I’ve found this method to work extremely well. It eliminates the need for any kind of screw fasteners which typically result in cracking the material, provides a nice clean look and allows the poly / acrylic to expand and contract with temps without issue. The specific tape I used…

Making New Portlights

This is part 1 of 2 showing the process for making new frameless / fixed portlights. Is this episode it’s all about the cutting and shaping which generally isn’t very exciting, hence the short abbreviated video 😉 Installing them will be a bit different! The material I use for all my portlight installations is a product called Makrolon GP made by Sheffield Plastics. In this instance it was a 3/8″ polycarbonate, but this material is available in many other thicknesses. The one thing that I…

Can Gelcoat And Epoxy Bond?

video thumb

Here is the first of 2 video’s where I look to see if there’s any truth to the belief that polyester based materials (such as gelcoat) won’t bond to epoxy. It’s been long believed that if you were using epoxy for your fiberglass repairs, you were more or less limited to having to use paint as your topcoat. Over the years I’ve “broken the rules” on occasion and to date have not had any issues using gelcoat as my topcoat over epoxy. I’m not saying…
