Shine & Protect in One Wash

Nanolex WashCoat is the original wash-on sealant booster, engineered to save time whilst giving a long-lasting gloss and hydrophobic layer. Apply after your wash and watch the sealant bond to paint, glass, and trim, forming a slick protective layer that repels water, dirt, and road grime. The foam will appear to bead off in front of your eyes.

Whether topping up an existing ceramic/sealant layer or use as a stand-alone solution, Nanolex WashCoat keeps cars cleaner for longer and speeds up drying. Great for enthusiasts, daily drivers, and professionals who want maximum results with minimum effort.

Not what I as expecting

Usually use Fireball Hydrophobic snowfoam as my contactless lsp after my final wash & rinse. Unable to replenish my stock of said product, so having read the reviews on here with regard to Washcoat - bought some. Have used it twice now. On both occasions came out as a foam, but upon contact with paint work, large holes appeared and the Washcoat evaporated before my eyes. After the recommended 3 minutes it looked as though someone had poured pint of milk over roof of my car. I followed recommendations 50-100ml initial application. Temp was about 9 degrees and in the shade. Same thing happened when washed car again yesterday. I use Bathe+ shampoo which was throughly rinsed off - so maybe Washcoat not suitable with the SI02? Have bottles of Cure & C2 - so after next week's wash will wipe one of these over my coatings. As title says not what I was expecting as Washcoat seems to have glowing reviews, but can only tell you what happened.

Quick and Easy to use

Such a quick and easy way to keep that protection topped up on your car, especially now the weather is turning and daylight hours reducing. This allows a more frequent / quicker wash routine whilst not compromising on ensuring the paintwork gets that required level of extra protection. I'm always looking to find ways of streamlining my wash routine and this product is a great time saver! More products like this please!

Absolutely Awesome

Absolutely awesome product. Used for first time this Sunday on my black Audi which has had 22PLE applied to the paintwork previously by Ultimate Finish, this product restores and enhances the already stunning finish after the build up of day to day grime.
