do your research mate before you attempy anything.
its not hard at all.
a mate did mine a few weeks back and the difference is unbelievable.
he used the dodo juice machine polisher with a product called lime prime first.
then a finishing polish after and its like glass,really stunning.
car was washed,and clayed prior to polishing.
you can also use something like 3m fast cut,but just go gently,and dont stay in the same place too long.
not rocket science,just polishing lol
