Car Care Instructions
Thanks for trusting the 4Bros with your vehicle! This guide covers ceramic coating, paint protection film (PPF), and window tint. Follow these steps to keep them looking their best, especially in the Arizona sun.
The First Days: Quick Rules
Not sure what you got? Ask us, or follow every box that applies.
Ceramic Coating
Your coating adds gloss, UV protection, and water-beading that makes cleaning easier. It needs time to fully cure, and it lasts longest with gentle washing.
Curing period
- First 24 hours: keep the car dry. Avoid rain, sprinklers, and washes. If it gets wet, gently blot with a clean microfiber towel. Don’t wipe.
- First 7 days: no soap washes, waxes, sealants, or spray products. The coating keeps hardening during this time.
- Remove bird droppings, bug splatter, and tree sap right away with plain water and a soft microfiber towel.
- Park in a garage or shade when you can.
Do
- Hand wash with the two-bucket method and a pH-neutral car shampoo with no wax (see Washing).
- Dry with a plush microfiber drying towel or a car dryer or blower.
- Use a coating-safe ceramic booster or topper every few months to keep the beading strong. Ask us what to use.
Avoid
- Automatic car washes with brushes or cloth strips. They cause swirls and scratches.
- Dish soap, degreasers, and harsh or high-pH cleaners. They wear the coating down faster.
- Waxes, polishes, compounds, and clay bars, unless we recommend them.
- Washing in direct sun or on hot panels.
Paint Protection Film (PPF)
Your ceramic-infused film protects against rock chips, scratches, and stains. Light scratches self-heal with heat.
Curing period
- Don’t wash the car for 7 days. This lets the adhesive bond and the edges set.
- Don’t touch, pick at, or lift the edges, especially in the first week.
- Small bubbles, haze, or moisture pockets are normal at first and usually go away within a few days to a couple of weeks as the film dries out. Warm sun helps. If you still see them after 2 weeks, contact us.
Do
- Hand wash with a pH-neutral shampoo and soft microfiber, same as the paint.
- Remove bugs, bird droppings, tar, and fuel drips quickly.
- Let heat work on light scratches. A sunny Arizona day or warm water often makes them disappear.
Pressure washer rules
- Keep the nozzle at least 24 inches from the film.
- Use a wide fan tip (25° or 40°). Never use a pencil or turbo tip.
- Never spray straight at film edges or seams. Spray across them at an angle.
Avoid
- Automatic brush washes.
- Abrasive polishes, compounds, rubbing compounds, and magic erasers.
- Solvents and harsh chemicals (lacquer thinner, acetone, strong degreasers) on the film.
- Waxes that contain dyes or petroleum distillates. They can stain or yellow the film.
- Ice scrapers, razor blades, or stiff brushes.
Window Tint
Your tint blocks UV and heat and protects your interior. The film needs a few days to dry and bond to the glass.
Curing period
- Keep the windows rolled up for 3 to 5 days. Rolling them down too soon can peel the film at the top edge. In cooler months, give it a little longer.
- Don’t clean the inside of the windows for 7 days.
- A slightly hazy or streaky look and small water pockets are normal during curing. They fade as the film dries, which can take from a few days to a few weeks depending on the film and the weather.
- Leave the rear defroster alone for the first few days.
Cleaning
- Use an ammonia-free glass cleaner (ammonia can break down tint) or mild soapy water.
- Wipe with a soft, clean microfiber towel. Spray the towel, not the glass, so nothing drips into door seals or electronics.
Avoid
- Ammonia-based cleaners (many household glass cleaners contain ammonia).
- Razor blades, scrapers, paper towels, or abrasive pads on tinted glass.
- Suction cups, stickers, or tape on the tint.
- Scratching the film with seatbelt buckles, rings, keys, or cargo when loading.
Washing Your Coated or PPF Car
Use this method on ceramic-coated paint and paint protection film, once the first-week cure period is over.
The two-bucket method
- Work in the shade on cool panels, early morning or evening.
- Rinse first to knock off loose dust and grit.
- Fill Bucket 1 with pH-neutral car shampoo and water. Fill Bucket 2 with plain rinse water. Grit guards in both are best.
- Wash top to bottom, one panel at a time, with a clean microfiber wash mitt. Use straight lines, not circles.
- Rinse the mitt in Bucket 2 before every dip in Bucket 1. That keeps dirt off your paint.
- Do wheels and tires last, with a separate mitt, brush, and bucket.
- Rinse well and dry right away with a plush microfiber towel or a blower. Don’t let water air-dry.
Never
- Automatic car washes with brushes or cloth strips.
- Dish soap, household cleaners, or old bath towels and t-shirts.
- Wiping dust or dirt off a dry car, even with a “clean” towel.
☀️ Arizona-Specific Tips
Heat, sun, dust, and hard water are tough on any finish. Here’s how to beat them.
- Heat: Never wash in direct sun or when the paint is hot to the touch. Soap and water dry in seconds and leave spots.
- Hard water spots: Our water is full of minerals. Dry the car right after washing, and use filtered or deionized water for the final rinse if you can. Keep sprinklers off your car. Remove spots quickly with a coating-safe water spot remover. Spots left to bake in the sun can etch into the finish.
- Dust and haboobs: Always rinse dust off first. Don’t wipe it dry, because the grit acts like sandpaper. For light dust between washes, use a coating-safe waterless wash with plenty of product and several clean towels.
- Monsoon season: Monsoon rain mixed with dust leaves muddy, mineral-heavy spots. Rinse and wash the car soon after a storm.
- Sun and UV: Park in a garage or shade when possible. Your coating, PPF, and tint add protection, but less sun exposure always helps.
- Bugs and bird droppings bake on fast in the heat. Remove them the same day.
