Will take more than one product.
Need to do a whole process the get the best out of you paint/
Wash and Clay to remove grime.
Polish to create gloss, shine and depth while correcting paint defects
Seal to protect the paintwork from elements and lock in the shine
Wax to further protect and enhance looks.
If there was one miracle product to do it this section of the forum would be worthless!
This is before you look into things like machine polishing, glazes, individual different waxes etc etc to enhance the looks further!
