I am going to be soon starting on my first fiberglass enclosure here in a few weeks. This will be going into my 1981 Ford LTD (big ass trunk

)It's going to be for my two 15" 15-PR154D Memphis subwoofers, it is going to be
about 7 cubes. The drawing is not to proportion it's just the basic layout how I want it.
Here is the basic design I have for it (I made the design in MS Paint and Adobe Photoshop).

I have the cylindars made for me already

. I found some tubes in my garage that fit my sub perfectly and I am going to fiberglass over them. I just need to get some wood rings cut for me because I don't have a router to cut circles and wood rings.
The material of the tubes is a real think cardboard (kind of like sonotube). Also here is a picture of one of the cylindar tubes I have, I was just going to paint it and fill in a gap at the bottom w/ body filler, but I changed my mind do to some persausion from some people on some other boards to fiberglass over this (inside and outside). I am going to have to cut a large hole in the sides of both tubes as drawn in the picture above.
This is a picture before sanding it and putting like 3 more coats of body filler in the "crevace" with body filler. Which after I got done filling it, I figured fiberglassing would be a good idea and I did all that body filler for no reason...lol

This will be my first attempt at fiberglassing so I have a few questions. What are all the things I will need? I know I will need fiberglass resin (two gal?), fiberglass cloth, fiberglass mat, and what else? How could I get the fiberglass cloth to stick to the tube while I am glassing it?
MEKP hardener, cheap paintbrushes, disposable plastic gloves and cups, them little respirator masks (i'm a glue sniffer but the stuff is strong so you may want to use it), some sort of eye protection for sanding...
(most can be found at autozone)
you don't have to get both mat and cloth, i don't think... and i don't know how well the fiberglass is going to stick to the body filler, i dobut it will honestly. But why do you want to fiberglass? i say just finish yoru enclosure and then paint it.
