Whoa guys its a speaker ring for a 3.5" speaker. Its not going to make a big deal if I dont use MDF. If you watch the first video I started off with MDF but it kept breaking because it was cut so thin.
And I would love to fiberglass my entire doors but I'm a high school senior, (no money
), and its still my dads truck technically. So I cant rip it apart. Plus I'm a first time fiberglasser.
I never thought about using just the resin. Ill give it a try if you think it will be strong enough. Would i need a few coats to get a good hardness?
