hi Alex! First of all i have to ask...... have you de-tarred/claybared the paintwork? Removing tar and then proceeding to claybar is a must before any polish hits the paintwork! if your unsure of a claybar and what it does,heres a quick run down,,,it is an engineered resin,designed to remove bonded contaminants from your paintwork,if you do not do this you are in effect slowly killing your paintwork... i do it 3times a year to my personal car....wash,bugs off,wheels washed,de-tarred,rinse,claybar wash rinse,and then polish! it may seem like effort,but truly worth it to look after your paintwork,the paint on these cars are notoriously thin from factory,although metallics are slightly better as they have primer colour and a clearcoat! i would myself personally recommend autofinesse products,they really are top notch,designed by a detailer for amateurs to professionals! however there is a small trick with paint colours......... White and other light colours,your better to polish and finish/protect the paint with a 'sealent; opposed to a wax! The reason for that is simply optimum clarity.. if you wax a light coloured car you never get that pin sharp finish because wax contains carnauba,which is yellow...it dampens the end result,so waxes for dark colours and sealents for light colours! you can use either or but i promise you will see a huge difference when the light hits your car I hope this helps,it is a little bit of a rushed reply as i have to pop out,any questions feel free to ask
