Fellow modelers,
There are many ways to apply fiberglass to your balsa sheeted structures.
My website (
www.arts-hobby.com) describes one of those ways. However, it is not the only way.
I added the step-by-step instructions for modelers who had never done fiberglassing and couldn't find a local expert to learn from. The method I describe works very well and provides a near perfect, long lasting, contest compatible finish. However, it's not the only way to do it . . .
For example, since creating the website instructions using Z-Poxy finishing resin, I have fiberglassed using WEST Systems 105 Resin with 206 Hardener. The WEST Systems epoxy dries much harder, is stronger and provides a more dent resistant fiberglass finish.
Does that mean Z-Poxy doesn't work? NO. It means WEST Systems provides a finish with different characteristics, that's all. Some of those characteristics I find beneicial. Other users may not.
Bottom line is this: you need to use the technique and materials that work best for you. If you have never done fiberglassing before, the instructions on the Art's Hobby website provides you with a process that works.
One more thing, on the 3+ day cure times I recommend . . . I have found the longer I allow the Z-Poxy to cure, the easier it is to sand without balling up or loading the sand paper. I've found that 5 days works great for me (and others who have used it in similar circumstances and weather conditions). If you get satisfactory results using less cure time - Great! Go for it.
