I use a lot of Meguiar’s products, but honestly the wax has been a total bust on the single stage original paint on my W123.

The spray on Products work pretty nice. I use ultimate waterless wash and wax, ultimate quik detailer and high gloss premium quik detailer.

The synthetic X-press spray wax is a great product, But it can be a little smeary on the old single stage paints. Since my old Benz sits outside the smear comes off after I wipe it down once or twice in the mornings.
