GYEON Q²M "PPF" Maintain (REDEFINED) Spray Sealant for Paint Protection Film 500ml

SiO² hydrophobicity for paint protection film with GYEON Q²M PPF Maintain

What is Q²M PPF Maintain? A SiO²-based spray sealant for PU and TPU paint protection films that refreshes hydrophobicity and self-cleaning after every wash to a contact angle above 80° — on matte and gloss film alike. Not for unwrapped clear coat or film edges that have already lifted.

GYEON Q²M PPF Maintain is a spray sealant from GYEON's REDEFINED line, formulated for polyurethane and thermoplastic polyurethane films. The SiO² content above 5 percent builds a silicate layer on the film that keeps the contact angle above 80° and stops organic grime from gripping. The pH range between 4 and 9 makes the sealant compatible with common coatings — unlike quick detailers for paint, which carry solvents or silicone oils that can attack the plasticisers in the film material.

• Contact angle above 80° after every pass. The SiO² content lays down a thin silicate layer on the film after two or three sprays. Water beads like fresh PPF, dust and road grime grip less, the self-cleaning comes back. You see the effect straight away in the bead shape the next time water hits the panel.
• Layering effect with regular use. A single refresh holds for over six weeks. Top it up after every wash and you build cumulative layers after two or three rounds — the standing time per application climbs, your consumption drops. That's the difference between care and a one-off.
• 30 ml per vehicle — 500 ml covers around 16 applications. Fine mist, lay it down thin, work it out with two cloths. No dwell time, no settling, no aromatic solvents. One bottle rides along with you for roughly six to twelve months through your regular wash rhythm.

Detailing1's tip from the shop: Don't spray the sealant straight onto the panel — hit the microfibre cloth instead. The product spreads more evenly, nothing lands on rubber, plastic or window seals, and you burn through less per round. Wash the cloths separately after use at 40 °C with no fabric softener — silicate residue gums up the fibres and kills the absorbency. After about 20 washes a cloth comes out of rotation. On dark film a fresh finisher cloth really pays off, because streaks show up there first under raking light.

Fine mist. Two cloths. No overspray.

Two or three sprays per panel are plenty — spray onto the cloth, spread the product across the film, then buff with a second clean microfibre cloth (350–400 GSM). No dwell time needed, the sealant bonds right away.

You can work the sealant wet or dry. Wet means: spray straight onto the damp film after rinsing, pick it up with the drying towel — water gets pushed off, streaks go away, hydrophobicity is live on the spot. This route saves a step and suits a quick top-up in between. Dry means: dry the car off fully, then spray and work it out in two cloth passes. The dry method gives you more control over big panels and is the clean call on dark film.

Temperature decides the result. Keep the film under 30 °C and don't work in direct sun — otherwise the carrier flashes off too fast and leaves specks that only a re-application after cleaning will shift. If you can't hold your hand on the film for a few seconds, it's too hot. Move the car into the shade, wait 15 minutes, then get going.

Works on gloss and matte PPF alike — the matte character stays put, no extra gloss layer forms. On textured films like carbon, spray thinner and buff harder so no residue sits in the grooves. Keep it off rubber, plastic and window seals — wipe overspray there off dry, because the SiO² layer on porous rubber seals leaves edges that only come off mechanically.

It cares for the film. Not the clear coat.

The sealant is chemically tuned to polyurethane, not to clear coat. On unwrapped paint the PPF formula brings no upside, because the SiO² layer doesn't bond to paint as well as it does to the film surface.

For clear coat, Q²M Cure is the matched choice — its SiO² content and carriers are set so they grip reliably on the harder paint surface. On hybrid vehicles with partly wrapped sections (front in PPF, rear in factory paint) you either go two bottles, two cloths, clean separation — or, more common day-to-day: Q²M Cure across all panels, because it works passably on PPF too. The other way round, no.

The spray sealant is compatible with ceramic coatings already laid down on the film. If the PPF carries a coating like Q² PPF EVO or Q² MOHS, the Maintain layer slots into the same matrix and acts as a topcoat. The coating underneath gets mechanical protection, the surface tension climbs on top. You feel the difference at drying — a freshly refreshed panel dries faster and without water runoff marks.

Where Maintain isn't the right product: on film with visible blisters, lifted edges or delamination. No sealant helps there — that film belongs in the hands of the PPF installer. Light swirls in the film surface won't get pulled out by the sealant either; the glossier surface makes them stand out more. Care then has Q²M PPF Renew as a polishing step before it.

Your standard after every PPF wash

The sealant is the right call for anyone who runs PPF regularly and doesn't want to watch the hydrophobicity collapse after twelve months. The rhythm is simple: refresh after every wash — and the car stays in showroom condition for good.

As a complete solution it slots into a three-stage system: Q²M PPF Wash as a pH-neutral shampoo with no gloss booster, so it doesn't attack the Maintain layer. Q² PPF EVO as a two-year coating for the base. And Maintain as the regular refresh after every wash. These three stages stretch a film's lifespan well past the manufacturer's warranty. If you've sunk four or five figures into PPF, this protects the investment — not the paint underneath.

Where the sealant fits less well is on vehicles that only move every six months. There a pure coating solution like Q² PPF EVO does the job without regular refreshing, because the wash-&-maintain routine then doesn't rack up enough applications per year to cash in on the layering edge. For pro detailers with PPF fleets in daily use there's also the 4-litre refill version on request — consumption stays the same, the price per millilitre drops noticeably.

Run the numbers: a 500 ml bottle covers around 16 applications at 30 ml per vehicle. Refresh weekly and one bottle lasts about four months. Work every two weeks and it holds half to three-quarters of a year. That makes Maintain the cheapest part of the overall PPF protection — the film itself runs four to five figures, the coating three, the refresh under two euros per application.

Application of GYEON Q²M PPF Maintain

Wet or dry – both bind instantly

The sealant works in two ways. After a hand wash with pH-neutral shampoo like Q²M PPF Wash, spray directly onto the wet panel – two to three sprays are enough – and wipe off in one direction with a drying towel. Water and sealant leave the film together, and the hydrophobicity is immediately active.

Dry application is the cleaner choice for dark films. Thoroughly dry the vehicle, then spray panel by panel, spread with a short-pile microfiber cloth (350–400 GSM), and polish with a second, clean cloth until no streaks are visible in glancing light. No dwell time is needed – the SiO² layer binds during the polishing process.

Dosage: approximately 30 ml per vehicle. A 500 ml bottle therefore lasts for around 16 applications, providing a four-month supply if used weekly. Do not spray directly on rubber, plastic, or window seals; immediately wipe off any overspray there with a dry cloth to prevent silicate marks from setting on porous surfaces.

Temperature rule: Keep the film below 30 °C. Do not apply in direct sunlight or on hot film after a long drive. If you cannot hold your hand on the panel for several seconds, it is too hot – move the vehicle into the shade, allow 15 minutes to acclimate, then work. Wash cloths separately at 40 °C without fabric softener; remove them from rotation after approximately 20 washes.

Notes: Do not spray on damaged or lifted film edges – consult a PPF installer first. Do not mix with or re-work with quick detailers from paint care products; their solvents can leach plasticizers from the film. Do not use long-pile plush towels, as the fibers will bind the product and smudge it. Store frost-free at 5–25 °C, sealed for 24 months.
