Wow............... look what i've started!
ok so i have a black car, always use meguiars gold class wax, however just switched to Nxt Gen wax (also by meguiars) i cant really describe my
problem if i say its like the car smears ppl will think i've jst not wiped the wax off enough, on a suuny warm day, after car has been cleaned i can get a terry towel and i can smear the wax that was on their from previois waxes, it leavs an uneaven black to my car, if i concentrate on the area with pressure i can sorta change the colours of black it produces, the paint work on my car is fine,
see some times walking up to the car in the sun you can see almost patches of wax build up ok so maybe im not making much sense!!
Oh and by the way in attempts to remove iy i've used
Meguiars stage one cleaner
Meguiars Deep crystal cleaner
Scratch X (thinking it may be a bit like T-Cut)
elbow grease
Boiling water (just thinking wax metls in hot temp and it may just lift it off)
Fairy Liquid
