I like my big black bumpers, but I don't like how heavy they are.
I was thinking that I could make a fiberglass mold out of the steel insert, and then fill that with some high density foam, like modern bumpers. Put it back in the rubber insert, and call it a day. Problem is, I don't know the first thing about laying up fiberglass. Help? Zach |

You can buy sheet urethane foam from airplane building suppliers. you can glue it together with bondo or polyester glazing putty and shape it with a surform file (cheesegrater) and then finish it with sand screen and sandpaper. Urethane foam works with polyester resin, styrofoam works with epoxy resin. You can't shape styrofoam (polystyrene) with sandpaper, you must cut it with a hotwire. Look at aircraft spruce's website, composites, and then foam.
Epoxy will melt urethane, polyester will melt styrene. So you can form your foam and then glass right over it just like a surfboard. Sand the fiberglass to shape, put a gloss coat of resin over the top, sand and paint. |
