I haven't got a pic of one yet but this is my plan




Clear bonnet painted to match the car but some of it cut back to plastic

[mini-man-dan]

I put a quick PhotoShop style pic on the Facebook page a few weeks back (white mini with blue and red/chrome engine). I looked into it and there are some kicking about made of 'lexan' which is suitable for everyday use but is more brittle than poly so a decent sized stone could crack it but then again the 4x4 crowd in America use them so they must still be fairly rugged, just haven't found any in the UK yet, or anyone making them

Info on lexan quoted from ehow;

Lexan is a brand name for a polycarbonate sheet of plastic. This plastic sheeting is durable, heat resistant, and so impact resistant that some "bulletproof" glass is made of Lexan. It comes in a variety of thicknesses, though the thicker the sheet, the more durable (and expensive) Lexan tends to be.

As said above, Lexan is a brand of Polycarbonate, probably the most well known brand name.

The only resson I'm doing it is so I can fit the bonnet at a show and walk off not worrying about people touching anything.

They would be show use only as polycarbonate will discolor and even melt with engine temps. price wise they would be about the same as earlier in this thread around £100

Not too sure how you plan to do this as Poycarbonate is much much more difficult to form than acrylic, hence why we still don't form windows. You will end up with very small bubbles all over the surface of the plasic unless it is dried out at a certain temperature before then heated to another specific temperature for forming. If you have access to a large oven with accurate temp controls then you're onto a winner. If you plan to do it with a hairdrier you're out of luck!

I would form them from acrylic (perspex) if you really wanted to do it, just be careful it doesn't crack.

The heat from the engine would be too great for any clear thermoplastic I can think of.

Another one to consider is PETG sheet. Without research I don't know the melting temp of that compared to acrylic or polycarbonate.
