if your struggling to get collinite off then your applying too much
What would you recommend for my Tornado Red GTI on the previous page? I want some good wax, better than the Megs stuff i currently use but i dont think my budget stretches to the supernatural.
Would you recommend Colli or any other Dodo wax?
have a look at a mk2 i did a month or so ago
http://www.golfgtiforum.co.uk/index.php?topic=159011.0 the pics dont do it justice as it looks redder than that in the flesh but it gives you a rough idea

i used purple haze pro which is more durable than the core 8 range but needs around the same curing time as supernatural and requires a second buff.
you need firstly get all your polishing done then get some collinite 845 or 476 layered up to really seal the paint then once a month or so give it some dodo wax to bump the gloss up along with the protection.
as chris said the soft waxes in the core 8 are very good,i highly recomend purple haze and rainforest rub!both are awesome waxes.
