Pillar Build Materials

Ok, so those that follow my build log know I have to replace the pillars I had built. I have never done any fiberglass work, so I don't really know what to buy and how much. I've watched a ton of videos and read some old forum posts and came up with this this. The plan is to also build a custom sub enclosures eventually, so their may be some things in here that are not necessary for a pillar build. I'm going to buy from Amazon since I don't have to pay shipping and I can get it in a day or 2.

So, here is my list. If there is a better product or if what I have selected isn't necessary, please speak up. If I need more of something than what I have listed, please tell me. I would rather have to much than not enough. I'm also going to buy the materials for the sub enclosure except the resin as it has a shelf life.

* means I bought it and used it.
** means I bought/was given and found it indispensable, I would not build without it.

**Dremel MM50 Multi-Max with 60 and 80 grit sanding paper (This thing saved so much time knocking down all the high spots and contouring my pillars) (There are other brands, I just happen to already have one)

*3ea Painter's Tape 2"

**Aluminum Foil Tape (Not sure exactly what brand I used as I already had it, but this stuff works great for shaping and keeping surfaces clean)

*MEK bottle

*32oz Mixing cups (12ea)

*2" Chip Brushes (36 pack)

1708 Biaxial Mat (Sub Box Material)

*1Gal Polyester Resin + MEKP Hardner

*True Composites 1.5oz Chopped Mat 50"x15' (5yrds) Will 2 of these be enough for pillars and sub enclosure?

**Evercoat Rage Gold 128Fl Oz for finishing filler Please tell me if 128floz is too much, this crap is expensive.

**Duraglas 128FL Oz for bulk filler

*Clean Sheets 12x12 mixing pad (I was using something else and decided to get this, I don't know why I waited as it was super easy to mix the next batch)

Evercoat Keg Blue Hardener

Rexco Partall Paste #2 Mold Release 12oz (Sub Box Material)

*5" Sanding disks (60 through 320grit)

**Eagle MAXCUT Kovax sanding disks. (Was sent a couple of these by another member, and they are very very good, went through about 10 of the Golds for every one of these)

**Sunmight Ceramic Film (Another item that was sent by a fellow member, and this stuff is very good also)

*7 Mil Nitrile Gloves Large (These kept tearing)

*Bondo Spreaders

**Plastic Cards (better than the Bondo Spreaders, especially on curved surfaces)

*Grill Cloth (for shaping pillars)

**CA Glue (I already have this on hand, but adding to the list)

*Precision Bottle for CA Glue application (Once I started working, I found that I wanted more precision with the glue application)

*Wooden Dowel rods

*Sanding Mouse Mini Detail Sander

*5 inch Sanding Mouse

**Dura-Block Round Sanding Block (This was great in combination with the Sunmight Ceramic for shaping curved surfaces. Mine was cut in half to fix the Sunmight perfectly)

*Dura-block Sanding Block 5.6"x2.6" (Also used with the Sunmight Ceramic Film)

**Jumbo 6 Inch Wooden Multi-Purpose Popsicle Sticks (Multipurpose, but mostly use for mixing resin)

200 Pcs Natural Wooden Food Grade Craft Sticks

*1/4 inch Chopped Fiberglass Strands (Used with Cabosil to make a paste)

*Cabosil - Fumed Silica Thickener (Mix with Resin and chopped glass to make a paste that can be used for build up or milkshake alternative. The paste will add strength when mixed with chopped glass)



Wrapping Materials

*Mellotone Premium Black Speaker Grill Cloth

*3M Hi-Strength 90
