- Will it melt the foam? I didnt get dow blueboard, but I got Owens Corning foam insulation instead. It looks the same to me, only pink. I'm thinking of doing a test on a small piece to make sure tho.
- Which fiberglass cloth do i get? DO i get the fiberglass cloth or the fiberglass mat? The cloth is thinner, and the mat is thicker and more woven. The only reason I'm adding fiberglass period is for strength in the weapon so it won't snap in half like it did last time. Which would work better? I dont want to get anything heavier than i need, but I dont want to sacrifice strength again and make adding fiberglass pointless.
- How easy is this crap to sand? I broke my power sander refinishing the first tessagia, and I am not counting on getting another one anytime soon. Please let me know what kind of work i'm getting myself into.
Ok, thats about it. Thanks.
Fiberglass mat is designed for strenght and fiberglass cloth is designed for smoothness.
Ideally you should put one layer of mat down, and then one layer of cloth over it
It should be about the same effort to sand as the older tessaiga or a little less. You dont have all the unnevenness and roughness you had with the bondo. Just make sure you sand the styrafoam down to the shape you want it: you cant layer the fiberglass mat and cloth repeatedly like you can with the bondo.
If the Fiberglass bondo didnt melt the foam then this stuff shouldnt either. Test it out first though.
