Full Description

The 303 Aerospace Protectant is a premium UV protection and surface dressing designed to preserve, restore and protect vinyl, rubber, plastics, fibreglass and exterior trim surfaces against fading, cracking and environmental damage. Originally developed for demanding marine and aerospace environments, this advanced protectant is widely trusted by detailers, boat owners and automotive enthusiasts looking for long-term surface protection without greasy residue.

Expert Notes

303 Aerospace Protectant is a water-based UV protectant for vinyl, rubber, plastic, gel coat, fibreglass, carbon fibre and finished leather. It dries to a clear matte finish rather than a wet shine, which suits dashboards, door panels, tyres and trim, and it is also used on boat seats, spa covers and patio furniture. 303 states it blocks up to 98% of UV radiation with proper, consistent use, and its anti-static finish repels dust and staining. The formula contains no petroleum distillates, alcohol, mineral oil or harmful silicone oils. Apply it to a clean, dry surface out of direct sunlight, then wipe completely dry, as it does not air dry. Pair it with a trim or interior cleaner and clean microfibre towels, and reapply every 30 to 45 days.

Perfect For / Suitable Surfaces

  • Dashboards and door panels
  • Tyres and exterior trim
  • Vinyl convertible tops
  • Vinyl boat seats and interiors
  • Hypalon inflatables and wetsuits
  • Spa covers
  • Outdoor patio furniture
  • Motorhome EPDM rubber roofs

Caution: Not for clear plastics, gauge panels, headlights, unfinished leather such as suede, canvas, fabrics or flooring. Keep overspray off glass, where it can leave cloudiness.

How To Use

Application

  1. Clean the surface and let it dry fully before applying 303 Aerospace Protectant.
  2. Work out of direct sunlight and lay a drop cloth under the item to catch overspray.
  3. Spray directly onto the surface or onto a clean microfibre towel.
  4. Spread it evenly, then wipe the area thoroughly and completely dry, as it does not air dry.
  5. Give it extra buffing to improve bonding, repellency and durability.

Aftercare

  1. If streaks appear, too much product was used, so remove the excess with a damp towel and buff dry.
  2. If streaks show after rain, wash the area with hot water, let it dry fully, then reapply and buff it completely dry.
  3. Reapply every 30 to 45 days to keep up UV protection.
  4. Remove any overspray on glass with hot water, a soft brush, then soap and water.
  5. Store the bottle closed and upright, away from heat and frost.

Top Tip: Buff until the surface feels dry to the touch, because leftover product is what causes streaks later.

Where should I not use it?

Do not use it on clear plastics, gauge panels, headlights, unfinished leather such as suede, canvas, other fabrics or flooring. 303 does not recommend it on fabrics because it is a water-based formula.

Does it contain silicone?

Aerospace Protectant. The product 303 is known for, in 296ml, 473ml and 946ml. 303 describes it as a water-based formula with no petroleum distillates, alcohol, mineral oil or harmful silicone oils, which dries to a clear matte finish, blocks UV to help stop fading and cracking, and repels dust and stains. It suits vinyl, plastic, rubber, finished leather and fibreglass, but not clear plastics, suede, fabrics, flooring, gauge panels or headlights. Spray it onto a clean, dry surface out of direct sun and wipe it completely dry, because it does not air dry; 303 says to reapply every 30 to 45 days. The same protection comes as Automotive Protectant 473ml and in a tub of 25 Protectant Wipes.

Trim, seals and tyres. Rubber Seal Protectant comes in a 101ml bottle with an applicator for door, window, bonnet and boot seals, and helps them keep their elasticity. Graphene Trim Coating is a non-greasy coating for faded trim that 303 rates at up to 6 months, and Tyre Coating & Protectant is a water-based, sling-free aerosol that dries to a satin shine with no brush needed.

Leather. A two-step system: Leather Cleaner lifts stains and preps the surface, then Leather Conditioner softens the leather and adds UV protection that 303 rates at 30 days. Both suit finished and unfinished leather.

Fabric and stains. Multi-Surface Cleaner removes spots of coffee, oil, grease and ink from water-safe surfaces, and Mold & Mildew Cleaner + Blocker removes mould stains without bleach. Fabric Guard restores water and stain repellency to outdoor fabrics, such as a convertible roof's seams, and is not for interior fabrics.

The Slick Shine Ceramic Detailer is infused with SiO2 and carnauba wax, works on wet paint as a drying aid or on dry paint, and is safe on matte paint.
