hm yes I'm not sure how over the top my friend is about this. Obviously we don't want any comeback, I am making my design as robust as possible and he can now see why I made certain choices that he initially thought to be OTT. The plan is to test this out on his own car(s) and then the company he works for will be interested in buying them off us for cars they restore, as the company he works for has insurance because they make their own stuff (could bassically build you a pre-ww2 astin martin from scratch if you asked them to) we won't have a problem as they are covered and aware of the situation. I am interested though in taking the product further once proven, my first outlet would probably be ebay or our own website. i'm not sure if a statement of the kind that we are not liable for any damages etc etc will cover us as I intend taking this in stages and giving it thorough testing before selling to any tom dick or harry so really insurance is just to make sure all is in order.
