Any thype will work coaxial, biwhatever idk the names the end result is the same
And get that roller that pushes the air out!
I would reccomend you the mat option
Any kind of cloth should work However I dont recommend you to use mat, any kind of the E-glass in the link you send will work S glass is stronger but more expensive…
Fiberglass can be a pain in the a?>*&^%! To make it a bit easier, use cloth, not mat and try Solarrez resin. Typical resin and hardner will start setting up in 6-8 minutes so it makes you rush (which you don’t want to do). Solarrez will give you time to get everything layed out properly as it does not setup until you expose it to sunlight. Also start small, maybe do a test piece so you can see what it is like to work with. It’s a trial and error process. You will fail a few times before you succeed.
