Having got some wd40 on the boot of my old car (dark blue originally... now dull blue with lots of white haze)- I noticed on wiping it off well it seemed to clean up the oxidized paint and bring up the colour pretty well... (easier than when I have previously tried with various polishes etc which usually don't work - especially as it either rains half way thru the job, or the sun comes out and bakes the polish on... or I'm in a rush between taxi-ing the kids etc)...
searching the web I notice that other people (USA?) have recommeneded such things as adding a cup of kersosene (std heating paraffin?) to a bucket of water and dishwashing soap, and washing the car with this, then rinse it off with fresh water to really clean up the paintwork...
Anyone tried this on a whole car... and can recommend it as an easier way than t-cutting the whole car... (if so presume that you then would finish it with a std waxing?) .... or is there really no substitute for lots of time and elbow grease?
thanks AJ
