Use code END50 for 50‰ off, some exclusions, end midnight 12/31
Mckee's 37 is a well known boutique detailing supply company with many great products. I have never know them to do a 50% off sale before.
Some of my favorite products from them:
SiO2 Auto Wash
N914 Rinseless Wash
Rinse free wash and wax
Trademark Extender Spray wax
Foaming wheel cleaner gel
SiO2 enhanced Tire Shine
Hydro Blue (spray and rinse ceramic coating)
All of there products are good honestly.
There ceramic coating is good too, although it can be tricky to apply in warmer climates.
