Polyester Resin - Bonding liquid that forms a good bond with fiberglass surfaces only

Organic Peroxide (aka MEKP, aka Methyl Ethyl Ketone Peroxide) - One of two initiators often referred to as catalyst and used to initiate polymerization of a resin.
in lamens terms it hardens the resin when mixed with it

Fleece - A term used for the fabric used as a base to apply your resin to. Common used materials are wooly fleece material, Tshirt material, and trunk liner. tshirt material is usually used for more angled items as where fleece is stronger but not as good for tight angles and is used for more rounded items and trunk liner is the strongest and comonly used in sub box applications.

Fiberglass Mat - A flat, coarse fabric composed of glass fibers. There are three types: chopped-strand mat, continuous strand mat, and surfacing veil. These are used to reenforce your project giving it strength. best if applied on the indide of the project if at all possible to avoid heavy sanding.

Thixsotropic Powder Cabosil, Aerofil, Talc - Powders used as a tickening agent to be mixed with resin you make a whipped consistancy. used for reenforcing your project. Talc is an alternative which is cheap but heavy, cabosil or aerofil are a little more expensive but will weigh less when applied to your project then the talc will.

Bondo - Of course it is used to fill dents in smashed up cars, but relating to fiberglassing, it is simply known as that goopy stuff used by most builders to fill in areas which need filling to create a smooth finish. Premium body fillers are prefered to the autostore standard bondo body filler. Rage Gold is a popular brand in the industry. this is mixed with a cream hardener similar to mixing resin with mekp.

Bondo Milkshake - This is a highbred mixture of body filler and polyester resin. You do not add the bonodo cream hardener to this mixture but will add the mekp. the mixture should be a dairy cream like consitancy and poured over the project and will creat a sheet of filler of the project making a very smooth final piece.

[b]40/40 - Duramix 40/40 is a gel plastic used to bond or repair plastics. Often used to modify dash panels. There are other companies but I dont know the names off hand. Duramix is now owned by 3M

Super 77 - 3M Super 77 Spray Adhesive or Super 99 are used to bond carpet to your mdf or fiberglassing project. It is suggested you aply to both the carpet and the item to be carpeted and allow it to start to tack before applying the carpet to the item.

MDF - Stands for "medium density fiberboard." MDF is an engineered wood made from compressed and bonded wood fibers. MDF is very dense and stable, allowing for very fine tolerances when machined. Used as a base in alot of fiberglassing projects and in sub box creations.

Router - a woodworking tool used to rout out (hollow out) an area in the face of a piece of wood. used to make speaker rings out of MDF that can be used as a base to apply your material over and resin.

Straight bit - a bit used in the router for cutting out the rings.

Roundover bit - a bit used for rounding the edges of your MDF to allow the fleece to run smoothly over the project.

Rabbiting bit - used around the edges of the MDF where the fleece will meet to create a flush connection.

Jigsaw - Power saw that cuts curved, irregular and intricate patterns with its thin blade that moves up and down. used in place of a router when a router is not available to cut out the speaker holes.

Tablesaw - A circular saw built into a table used for cutting the MDF straight cuts

Circular saw - A hand version of the table saw used as a cheaper alternative

DA Sandera sander used with a compressor to sand down the rough spots on your fiberglassingh project. When a compressor is not available an orbital sander will be the closest replacement.

Brad nailer - used to nail the MDF together.

Coarse drywall screws - Used when a brad nailer is not available

Countersink bits - used to predrill in the MDF before putting the screws in. Keeps the wood from splitting and crates a countersink to flush the head of the screw in the wood.

Staple Gun - used to mount the fleece to the MDF

That's right. Get the el' cheapo's from walmart. When the resin dries, give the cup a squeeze and it pops out. :)

1. Lots, and lots of rubber gloves
2. Good sharp scissors to cut mat,cloth,etc.
3. Chip brushes by the box
4. Circle jig for router
5. CA glue and accelerator.
6. More spray glue, as you can use it to adhere the fleece as well prior to the application of resin .
7. Lots of Patience ...............:)
