Coating or protectant
Gyeon describe LeatherShield EVO as a ceramic coating made for automotive leather, suitable for every modern leather upholstery, and say it will not alter the look or feel of the seats. Colourlock sell Leather Shield as a protectant for new leather against wear, abrasion and dye transfer from clothing, aimed at the driver’s seat, the bolsters and the seat cushions, and say to apply it within the first three years of the leather’s life.
Price against labor
By the bottle, Colourlock is far cheaper, at about $5.32 an ounce against about $35 for Gyeon. The case for Gyeon is labor: its 18-month rating means one application over a period in which Colourlock’s schedule asks for six on the high-stress areas.
Dye transfer
Both name it. Colourlock put dye transfer from clothing at the top of their listing, and Gyeon name dye transfer, UV damage and spills on their LeatherShield EVO Kit listing. The leather protectant roundup covers the wider field.
Who should buy which
- Apply once and leave it: Gyeon LeatherShield EVO, $59.99.
- New leather, bolsters and dye transfer on a budget: Colourlock Leather Shield, $26.99.
- A cleaner in the same box: Gyeon's LeatherShield EVO Kit, $104.99, adds LeatherCleaner Natural.
