Spoony, do take time to read all the info on how to apply the various lifeshine products. You need the car to be spotlessly clean, no wax in the shampoo, not windy, not sunny and a load of elbow grease. I’d advise you to buy Magma clean (Autoglym from Halfords) and add that treatment in after first wash and rinse, then magma, then wash and rinse again, + de tar the lower panels especially behind the wheels and was again, so that your prep is as good as you can get it before you seal the car. Did you get Carbon shield (a little goes a long way) 0r extra gloss protection. It normally takes me 8+ hours to do the complete job. good luck and send us some pics when its done.
