Make A GhettoBlaster Tricycle

Step 4 Fiber-glassing

Now this is the hard part.
We have to stretch the polyester over the whole speaker box and staple or glue it onto it to give it the desired shape, This was very hard in our case because of the odd shape of the speaker box.

Once you have it stapled into the shape you want, start to mix the fiberglass resin with the catalyst and start painting it onto the bare polyester fabric. After it has dried it should be abled to hold its shape.

Now you can start painting the fiberglass resin with fiberglass strips. We used 2 gallons of fiberglass resin and about 5 yard of fiberglass matting. We stopped doing fiberglass once we were unable to press on the fiberglass.

If you want to you can sand the bubbles from the fiberglass to help you later, we never did that and it made it much harder in the end.

Now you have to cover the whole thing in bondo. we used 3 paint cans worth of bondo for ours, this is something that takes alot of patience because alot of things can go wrong. Once you have it covering the whole thing we used 150 grit to sand it into shape then we used 600 grit to make it smooth. We had a total of about 3 layers of bondo in some spots to make it look smooth.

Then you need to cut out the holes for the speakers, for the big ones i used a reciprocating saw and a file and for the little ones i used a 2 3/4 inch circular drill bit. Make sure the speakers fit before you paint.
