Q² LeatherShield EVO is an advanced and re-worked SiO2-based formula specially developed for all modern automotive leather upholstery types. It provides superb protection against dirt, UV rays and the rigours of everyday usage. Q² LeatherShield EVO is now amazingly simple to apply, requiring only one layer. It’s designed for and tested on all modern types of leather, providing great protection and no change of feel or colour, leaving a fully OEM matte finish. Q² LeatherShield EVO does not stiffen, clog the pores of the leather or make it more slippery, maintaining the regular comfort of use. Do not use on open structure, aniline or semi-aniline leather upholstery. For such surfaces, use Q² LeatherCoat REDEFINED. How to Use Gyeon Q2 Leather Shield EVO: Ensure you clean the leather well and remove any excess of your cleaner. We highly recommend the use of one of our Q²M Leather Cleaners. Make sure you proceed with a test panel before you apply the product to the whole upholstery. TIP: Apply the product to one panel at a time and ensure even coverage. Do not wipe off. If you see the product drying unevenly, level the product without adding more liquid. Check after 20 minutes, if necessary - wipe. For advanced users, I would recommend using a Q²M MF Applicator.
