the meguiars quick clay should be ok for you then follow it with dc stage 1 and 2 then finish it with nxt tech wax. use the endurance tyre gel and buy a wash mit and nxt tech wash.
another top product halfords sell is zymol cleaner wax this is excellent stuff , it also eaves a longer lasting finish then megs i alternate between both.
1 dc step 1
2 dc step 2
3 nxt tech wax
if this gear is included buy these
1 wash mit (lambswool or microfibre)
2 nxt wash
3 supreme shine microfibre
