IDk what else you would use to build a frame or skeleton. I use MDF, thickness pending on what i am making. Whatever you use, You have to keep in mind it has to hold up to the build. Will it flex? If it is too flexible, the resin will warp it as it catalyses. Also, will it adhere? The frame and fleece and resin must make a bond. Without this you will have leaks and or the box will fall apart at the meeting point. Always, remember to soak well the areas where the fleece meets the frame to ensure a good bond. I always start at all my bonding points and then work through. Make sure you dont mix your resin too hot. This will cause it to dry too fast. Dont over due the resin either, you gotta move kinda fast, if the area starts to catalyze, you need to move on and quicker. You dont relly want to brush over areas that are drying. It will start to chunk up. As you learn I am sure you will see it. Like I mentioned before, it will be a learning experience and you will learn as you go what works best for you. Thats just a few tips that will help you out. Have fun building!
