The fiberglass cloth is known as mat or roving(coarse). For smooth finishing you need c-veil or add air dry or wax to the resin

You also need rubber gloves, brush or paint roller , acetone or DBE for clean up. Otherwise you will be using lots of brush and paint roller foamy as the resin will be harden between 20 to 30 mins depending on how much catalyst(hardener) you are using. You will be needing wax if your project is from a mould so it can be released. you will need a few different size rollers to roll away the air bubbles. You will be needing diamond coated air tools cutting/trimming. You also need a grinder to grind away flaws. Lastly you will be needing N95 dust mask so you don't breath in the dust If you are doing grinding...better wear Tyvek cover all(suit) so dust don't get onto your clothing. Otherwise you will be scratching like crazy
