RejeX Frequently Asked Questions (FAQ)

Does RejeX contain UV inhibitors?
RejeX is a tough, air-cured, impermeable high-gloss, ultra-slick polymer sealant and finish without UV inhibitors. It provides unmatched protection against surface deterioration; easily outlasting and outperforming most wax-type products. As a result of heightened durability, RejeX lasts longer, shines brighter and protects better than waxes and inferior polymer-based coatings. Waxes have a limited lifespan as they oxidize and “die” when exposed to light and oxygen. As wax coatings degrade, they lose their ability to enhance and protect surfaces from environmental damage.

Excellent for use on painted surfaces; RejeX retards the oxidation process virtually sealing out water and oxygen. And nothing compares to a RejeX shine! The high light refractive index means that the majority of the light spectrum (including UV radiation) is being rejected from the surface rather than being allowed to penetrate into the paint (or fiberglass, etc.). Use it on your car, RV, boat, motorcycle, airplane, helicopter, and 4-wheeler ATV to protect your investment and leave an extraordinary shine.  

Should RejeX be used on oxidized paint?
RejeX is non-abrasive and is not designed to compound or revitalize “dead” oxidized painted surfaces. Compounding products (i.e. polishes) are designed to take off layers of oxidized paint with solvents and abrasives. RejeX is effective on all non-porous hard surfaces; it is safe to use on glass, fiberglass, plexiglass, Eisenglass (the clear vinyl windows used on boat canvas and some convertibles) and all clear-coat (gel) finishes.

Can RejeX be used on porous surfaces?
RejeX is an air-cured sealant and as it cures a light haze forms at the surface.  While no buffing is required to develop the shine, the haze is wiped off after about 10-15 minutes.  On porous surfaces, the dried RejeX haze in the pores, cracks and crevices can be difficult to remove by wiping.

What makes a RejeX protected vehicle easier to clean?
RejeX sealed vehicles are armored with a tough polymer film coating that’s so non-porous and slick that most contaminants can’t penetrate or stick to it. Bug splats, tree sap, exhaust deposits, bird droppings and other harmful contaminants won’t penetrate RejeX. So, while dust, dirt and other contaminants may still settle on your vehicle, they can’t penetrate the sealant to damage the paint and they sure won’t be able to stick to the RejeX film. Cleaning RejeX’ed vehicles is just that quick and easy. And, the shine will last and last.

Can you use RejeX over wax?
Oh my gosh; why would you?  While RejeX can certainly be applied over wax and give you the benefits of enhanced gloss, superior protection for your paint and rejection of stains (bug splats, exhaust deposits, belly grime, etc.), it’s better to put RejeX right on top of the paint.

Waxes are softer, less durable films than RejeX. RejeX, when put on top of wax is dependent on the wax holding up and it will degrade long before the RejeX. When the wax “dies”, the RejeX bonded to the wax will come off.  RejeX, when bonded to paint will outshine, outlast and out repel wax so why not harness the full potential of the RejeX coating. Get maximum results; use RejeX instead of wax.

Is there any benefit to applying a second coat of RejeX?
You bet there is added benefit; you have to see it to believe it! Subsequent coats will deepen the luster and by layering up will provide more protection and longevity. It is important however to ensure RejeX cures fully before applying subsequent coats.

How much will I need to treat (various size vehicles)?
The RejeX film is very thin (less than a micron), so a little goes a very long way. For one coat, a 16 fl oz bottle should cover:

  • A single engine airplane tip to tail
  • One 25’ boat or RV
  • 2 SUVs or sedans
  • 3 economy or sports cars

Can RejeX be used on the 3M Diamond Plate product used to protect the front of RVs?
Yes, while the Diamond Plate shield is very good for protecting paint from small rocks and other particles that can chip paint, it is quite difficult to clean bugs (and other contaminants) off it. Customers swear by RejeX’s super-slick formula for making cleanup easier and for keeping their RVs looking great. 

How long will RejeX last?
Longevity varies depending on surface preparation, product application and environmental conditions. For best results, attention should be paid to:

  • Surface preparation  - surfaces should be cleaned of surface grime, stains and oxidation and dried completely

  • Surface condition – surfaces should be dry, out of direct sunlight and optimally less than 85oF

  • Cure time - RejeX should be allowed an initial 10-15 minute prior to wiping the haze and an additional 8-12 hour cure to final hardness

  • Storage conditions – vehicles and aircraft stored indoors (garages, hangars) will remain protected longer than those stored in outdoor, adverse conditions.

  • Maintenance operations – Washing frequency, washing method and cleaner used

  • Operating conditions – What kind of contaminants is the vehicle exposed to? The more challenging the environment (hail, snow, ice, sand, “love bugs”, etc.); the more frequent RejeX may need to be applied.

Generally, RejeX lasts between 6 and 8 months, although we have numerous reports from customers who say it has lasted over a year. High abrasion areas, like leading edges airplane wings, require more frequent application – perhaps every 3-4 months.

What happens if my vehicle gets wet before the 12-hour curing interval is complete?
RejeX is an air-cured sealant and reaches full cure in about 12 hours. The longer it cures, the stronger the finish. Prior to full cure, the film is softer and less protective and longevity can be compromised. Don’t worry if the sealant gets a little wet while it’s curing (e.g. a light sprinkle or dew), that will not be a problem. Do avoid heavy rain, parking the vehicle under a tree where the sap will get on it and driving long distances where exhaust and road grime will get on it. Regardless, RejeX cured even just an hour or two will significantly outlast waxes and inferior polymer coatings.

Will RejeX clean my vehicle?
No, RejeX is not a cleaner. It is important to get your vehicle as clean as possible prior to application. RejeX leaves an incredibly durable protective barrier, but it will seal in stains just as effectively as it seals them out.

Will RejeX keep the black streaks off my RV/motor home?
RejeX sealed vehicles are armored with a tough polymer film coating that’s so non-porous and slick that most contaminants can’t penetrate or stick to it. Black streaks, bug splats, tree sap, exhaust deposits, bird droppings and other harmful contaminants won’t penetrate RejeX. So, while the black streaks may collect on your RV, they can’t penetrate the sealant to damage the paint. While it won‚t keep them off, cleaning RejeX’ed RVs is just that quick and easy. Like most soils, black marks will rinse off under a garden hose or wipe off with a wet rag.

Will RejeX keep hard water (mineral deposits) off my boat or car?

RejeX sealed vehicles are armored with a tough polymer film coating that’s so non-porous and slick that most contaminants can’t penetrate or stick to it. Hard water deposits (calcium and magnesium salts) and water spots will be greatly reduced and generally wipe right off.

Do I just put RejeX on the leading edges/front or on the whole vehicle?
RejeX, when used on the front and/or leading edges provides great protection and makes clean-up, especially of bug splats, easier. To make bug removal easy, some people start using RejeX on the front of their cars and RVs, and on the leading edges of aircraft. However, once they appreciate the protections afforded by RejeX and see the deep, reflective finish, they can’t resist doing the whole vehicle.

You state that RejeX needs to cure for twelve hours "out of the elements." This seems to indicate that it is not suitable for use unless the vehicle being treated can be stored inside for the prescribed period.
By “out of the elements” we mean to avoid direct sunlight that could heat the application surface excessively. Don’t apply RejeX when there’s a probability of imminent rain. Don’t park the vehicle under a tree where sap can drip on it. In short, RejeX is usually applied outdoors. But it’s important to select a good day and apply RejeX in an area where it’s not likely to get stains on it until it has had the chance to cure for at least several hours
