Start from Zero

Our Prep Spray helps you to put on a pristine, uniform protective coat by removing all old polish, wax and sealant from the surface of your car. Often, these spent leftovers can clog up the pores of your surface, which reduces the effectiveness of a new ceramic coat. In addition, small amounts of old polish or sealant can hide imperfections in your paintwork, such as small scratches or swirls which need addressing in order to get the maximum amount of protection. Proje Prep Spray ensures that everything is removed, so you can start again from zero.

Protect as you Go

The natural lubricating agent inside Prep Spray ensures that you aren’t running the risk of introducing new scratches or defects as you remove old residue from your paintwork. This means that you can work more effectively and put a bit more effort in without any concerns that you might damage your paintwork.

Prepare for Perfection

Having a completely stripped surface before applying a new ceramic coating is the best way to ensure long-lasting results. By using Prep Spray, you can buff out any imperfections before adding a ceramic coat, meaning you’re left with perfection and a layer of protection that lasts up to a year.

How to use
Car Prep Spray

Using Proje Prep Spray
is quick and simple.

Make sure you’re working on a clean,
dry surface by washing your paintwork
first with Vital Car Wash Soap.

Prep Spray can be applied directly to the surface
of your vehicle. Simply spray, wait 30 seconds to a
minute, then wipe away with a clean microfiber
cloth. Don’t worry about applying too much
pressure; the natural lubricant within Prep
Spray ensures that there is no harmful friction.

Repeat until the entire area has been sprayed.
Now, you’re ready to apply your ceramic coat.

This takes the anxiety of when to buff off from “flash times.” I purchased the prep and ceramic bottle bundle, and the process was extremely easy, leaving a deep and glossy shine. I saw the ad on social media and decided to give them a chance, I’m glad I did! I’ll definitely be using their products for a long time.

I was skeptical when I first saw the ad for the ceramic coating, I purchased a bottle and tried it and I was amazed by the results! I almost purchased a tiny bottle from another company for over $150 I am glad I came across this before I did! Yes I use proje products on my nissan skyline r32!!

This stuff is amazing. I’ve tried a few other sio2 coating and of course butter wax and things. But this stuff blows them all away! Awesome shine. Awesome hydrophobic properties. Nothing wants to stick to my truck now. Just wash away with water! Awesome product! I’m satisfied.
