I'm not saying they will cause him trouble, they aren't very complex at all, but it would take anyone a fair amount of time to create the moulds and to trim each spat with the precision it would need for good fitment. That, combined with the low demand, makes them uneconomical at the price people are willing to pay IMO. I would advise him to take deposits before investing his time and money into it too.
I was only going to make them if they were as close as possible to the OEM ones with the same fitment method and everything included to do it properly. If you don't use the foam to attach them I think they may look a bit crap as you will have a bead of sealant visible opposed to an equal 2mm gap. The only alternative to this is to get the whole rear bumper painted after they have been bonded on. I'm sure he will realise this though and consider it beforehand.
I did a course courtesy of work on composite materials, carbon and kevlar in particular. It's amazing stuff when used in the correct way, which is with as little resin as possible. The best way to do this is by using the vacuum method and you get the lovely dry carbon finish too. :smitten:
The carbon parts you see with a gloss finish have next to no additional strength from the carbon - its mostly from the large amount of resin they contain.
