Expert Notes

303 Automotive Protectant is a 473ml UV protectant for the rubber, vinyl and plastic surfaces of a car, inside and out. It dries to a natural matte finish with no oily or greasy feel, so it suits dashboards and door trim as well as tyres, wiper blades and weather seals. 303 states it helps prevent fading, cracking and discolouration, repels lint, dust and staining, and contains no harmful silicone oils. It shares its formula with 303 Aerospace Protectant. Use it after an interior or trim cleaner, apply out of direct sunlight and buff completely dry with a microfibre towel, since it does not air dry. Keep it off clear plastics, gauge panels, headlights, fabric and flooring, and reapply every 30 to 45 days.

Perfect For / Suitable Surfaces

  • Dashboards
  • Interior vinyl and plastic trim
  • Exterior plastic trim
  • Tyres
  • Wiper blades
  • Rubber weather seals
  • Finished leather

How To Use

Application

  2. Work out of direct sunlight on a cool surface.
  3. Spray 303 Automotive Protectant onto the surface, or onto a microfibre towel when working near glass or gauge panels.
  4. Wipe it evenly and thoroughly across the area.
  5. Buff dry with a clean towel, as the product does not air dry.
  6. Give it extra buffing to improve bonding, repellency and longevity.

Aftercare

  1. If streaks appear, remove the excess with a damp cloth and buff again.
  2. Reapply every 30 to 45 days for continued UV protection.
  3. Clean treated areas gently with a suitable interior or trim cleaner between applications.
  4. Keep towels used on tyres separate from those used inside the car.
  5. Store the bottle closed and upright, away from heat and frost.

Top Tip: On dashboards, spray onto the towel rather than the panel to keep product off the windscreen and gauges.

Frequently Asked Questions

What size is this bottle?

This 303 Automotive Protectant is a 473ml bottle, the 16oz size in the 303 range.

Can I use it inside and outside the car?

Yes, 303 lists dashboards, trim, tyres, wiper blades and weather seals as ideal uses. It works on vinyl, plastic, rubber, finished leather, PVC, gel coat and fibreglass.

What finish does it leave?

It dries to a natural matte finish with no oily or greasy feel. It is designed to restore and maintain original colour and texture rather than add gloss.

Where should I avoid using it?

Do not use it on clear plastics, gauge panels, headlights, unfinished leather such as suede, fabric or flooring.

Why does it need buffing?

303 Automotive Protectant does not air dry, so it must be buffed dry with a clean towel. Extra buffing improves bonding, repellency and longevity, and any streaks can be removed with a damp cloth before buffing again.

How often should I reapply it?

303 recommends reapplying every 30 to 45 days to keep up protection against UV. Extra buffing at each application improves bonding, repellency and longevity.

Is it different from 303 Aerospace Protectant?

No, 303 states its automotive, marine and aerospace protectants share the same formula, benefits and application method. Only the label changes with the market it is sold in.

Does it contain silicone?

No, 303 states it contains no harmful silicone oils, which can dry out and damage surfaces. The shared 303 Protectant formula is water-based.

The Brand

303

303 is an American surface protection brand that has been a trusted name in its field since 1980. Its protectant was first developed to protect aircraft rubber wing boots at high altitude, and the formulas now care for cars, boats, RVs and outdoor gear. Since 2012, 303 has belonged to Gold Eagle Co., the Chicago company behind STA-BIL, which says its branded products, 303 included, are manufactured in the United States at its facilities in Chicago. The brand line is Proven to Protect.

At The Drivers HQ we stock 303 online with UK delivery and in our Ilkeston shop. Popular choices include 303 Aerospace Protectant, the Automotive Speed Detailer and the Slick Shine Ceramic Detailer.

303 protectants, trim and leather care

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.

303 detailers, coatings and wheel cleaners

Between washes. The Automotive Speed Detailer is mist-on, wipe-off gloss for paint, plastics, fibreglass, chrome and glass, with anti-static properties and UV blockers. 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. The Graphene Detailer tops up existing coatings, works wet or dry and lasts up to 90 days, and the Automotive Spray Wax cleans off water spots and dust and leaves protection rated at up to 90 days.

Coating. Graphene Nano Spray Coating is a graphene oxide based spray coating that 303 rates at 12 months. It is strongly hydrophobic, helps reduce water spots by lowering the surface temperature, can be applied in direct sunlight and also goes on glass, wheels and trim.

Wheels. Wheel & Tire Cleaner is a foaming, acid-free and non-corrosive cleaner for wheels and tyres: spray onto cool, rinsed surfaces, leave for 2 minutes, agitate and rinse. Heavy Duty Wheel Cleaner is acid free too, removes brake dust and caked-on dirt, and also works as a paint decontamination spray for embedded fallout before polishing.
