My first few went fine... interior neon, painting console and dash parts, sound system, the only very minor problem was getting the stuff out, after that it was a breeze.

Then there was the fiberglass incidents.... I was bent on building my own pair of fiberglass sub boxes. I sound deadened my trunk (about a day of cleaning and prep work) and had taped off and covered most of my trunk. It was my first attempt at fiberglassing anything. Just getting the trunk moulds was painful. I kept getting air bubbles in the fiberglass and trying to correct it, only leading to more bubbles. about a month and a half later (I had to work during the weeks), I finally finished the mould (7 layers) and started working on the mdf rings and the rest of the enclosure. The rings did not go well at all. I attempted a flush mount, and after about f'ing up about 4 times I got them right.

A month later I had a sad excuse for sub boxes, and then attempted to finish with body filler and paint.... the body filler went just as well as the glass (first time using that too)... after sanding over and over and reapplying I just got frusterated and left them. I only used one... it actually sounded decent. A year later the sub blew (apparently a manufacturers defect), and I decided to cut my losses and toss both boxes and start fresh.

At least I learned from it... but it cost me a sheiteload of cash in resin and glass... as well as many many hours of my life.
