Not so hard to do.....
CC:
The skill is involved in making the first mold. After that, it's not skill, just a chopper gun or laying up mat and mixing resin and the mold will most likely be plywood. Anyone could do it in the garage. It just stinks. Of course there is the paint issue. Ive been there with the paint before. Triumph uses British Standox colors. British Standox is a wholly owned subsidary of DuPont but DuPont, NA color formulary isn't interchangeable with British Standox. Consequently, each color has to have spectroscopically analysis and the mixing formulary custom written. Like I said, been there, done that on my sidecar.
I too really like the chin spoiler. Even a gel-coat spoiler with a wet scuff and a rattle can gloss black finish would work for me and look tits with the black, classic engine block.
