After several years of track work and long runs my cobra is now due for a respray (and filler of the million little stone chips etc) and I'm enquiring as to how much paint is required to cover a cobra. Don't need it down to last ml. just an average so I can get my colour mixed- Princess (Alice )Blue.

Sorry to say it, but the answer is like "how long is a piece of string". You need to clarify the following to your paint supplier:
1. Are you painting it in Direct Gloss (DG) or Clear Over Base (COB)? If DG, are you doing 2 or 3 coats?
2. If you using a colour-keyed primer or sealer?
3. Is the colour a solid or metallic. If metallic, you'll need an extra 1-2 coats to orient the metallic.
4. Is the colour you have chosen considered translucent needing more 'coats to hide'? If so, then if using COB you may need up to double the amount of basecoat to get full coverage. Obviously this will completely blow-out your paint requirements.
5. What paint system are you using? For example, PPG COB reduces 1:1, but Standox reduces 2:1.
6. If you're also painting under the bonnet & boot or any others areas that aren't the main body.
The above taken into consideration, you might use between 3 and 5 litres, but as mentioned, it depends on all of the above factors. I own a bodyshop and we paint both metal and fibreglass cars...and between 3-5 litres is about what we'd use.
PS> With regard to changing the product ratios....we categorically don't do it...with the sole exception of altering the amount of reducer (thinner) but within the product specs (ie. some systems allow between 0-30% reducer for example). Changing the product to hardener ratio is asking to open a HUGE can of worms. You can, however mix two of the same system hardeners together (ie slow and medium to make a semi-slow) or reducers.
