This is neat. I never played with fiberglass. Gives me some ideas for other parts. Is there any reason to use the glass shards over the mats or just a personal choice? Thanks. dennis
Well Dennis, honestly the "chop mat" is an easy way to build up thickness quickly and it's cheap cheap cheap - but requires body work at the end, unless you mat over it with a woven mat for the finale. Also, even with a woven mat on a complex small shape, you'd want to cut it into small pieces to use and overlap them. Fiberglass is weird stuff, especially for a carpenter like me, but I've used it to make engine boxes for boat restorations when the wood boat called for them. It's pliable stuff, and like you see here - it can use fabric to make a shape. Pretty simple stuff - but messy, and gross. Use the woven material if you can, but if you want it thick and dirty (kinda) use the chop. I've seen a lot of audio places use chop mat simply because it's faster to get the desired thickness, and costs less - then brush over a whole bunch of body filler.
