Want ceramic coating in Signal Hill without dropping the car at a shop for two days? Daji Mobile Detailing applies a 6-month SiO2 hybrid ceramic from $100, or a full polish plus 3-year ceramic package at $999 (normally $1,200). We prep and coat in your driveway, and the coastal salt air stops eating your clear coat.
What's Included
SiO2 paint protection that makes the finish slick, glossy, and a lot easier to keep clean. UV, grime, and water bead off.

βPatrick did an outstanding job detailing my carβI couldn't be happier with the results. My car had been through a rough winter and was in pretty bad shape, but he completely transformed it. The before-and-after difference is incredible. From start to finish, his communication was clear, timely, and professional, which made the whole process smooth and stress-free. He paid great attention to detail, and it really showsβmy car looks amazing. It's clear he takes pride in his work and goes the extra mile to make sure everything is done right. I would absolutely recommend Patrick to anyone looking for high-quality detailing and excellent customer service.β

Our Work
A mix of ceramic coating work and other details we've completed around Signal Hill. Tap any photo to view full size.
Why Daji
Mobile car wash and detailing across the South Bay, we come to you, driveway or office lot.
50-gallon tank and on-board generator on every job, so you need no water or power.
Owner Patrick does every detail himself, 5.0 across 32 Google reviews, no rotating crew.
Flat prices listed up front, no surprise add-ons, and 20% off your first detail.
Coastal South Bay salt air oxidizes clear coat fast, we wash and protect specifically for it.
Why Signal Hill
Signal Hill sits on a steep dome wrapped entirely by Long Beach, with working oil derricks still pumping nearby. That oily field dust and the marine haze off the harbor settle on paint fast, so hillside locals lean on regular mobile details to keep it from baking in.
Most Signal Hill jobs run in the townhome driveways and apron spots up the hill off Hilltop, Crescent Heights, and the Skyline streets. The grades are steep, so we chock the wheels and work the car flat at the driveway lip. For gated hillside complexes we coordinate the entry code ahead, and condo owners near Spring Street meet us in the lot.
Fine dust off the Signal Hill oil field settles on horizontal panels and bakes in under the afternoon sun on the exposed hilltop. We run an iron-decontamination pass on every car here to lift that oily grit out of the clear coat, then seal it so the next round of field dust rinses off clean.

FAQ
The 6-month SiO2 hybrid is rated for 6 months of UV and contaminant protection, longer with regular maintenance washes. The Polish & Ceramic Coating package ($999) lays down a 3-year coat after full paint correction.
Ceramic locks in whatever is under it, so any swirl marks or oxidation get sealed in too. A clay bar ($100) is the minimum prep. A one-step ($199) or two-step ($299) polish corrects the paint first so the coat goes over a clean finish.
For a spray SiO2 hybrid, yes. We control the surface with a clay bar and decon, then coat in a shaded, dry spot. For a multi-day, multi-layer professional coating a controlled shop is better, and we'll tell you straight if that's the right call.
One-step is a single corrective stage that removes light swirls, scratches, and oxidation. Two-step adds a heavier cutting stage then a refining pass for near-perfect clarity. Two-step costs more and takes longer because it removes more.
We watch the forecast and text you the night before if rain is coming. Light coastal mist is fine because we work under your garage, carport, or any covered spot. Heavy rain gets a free reschedule to the next clear day.
No. The truck carries a 50-gallon water tank and a generator. We detail anywhere with curb access: driveway, street, office lot, or marina. You don't have to be home as long as the car is unlocked or you leave a key.
It's the starting price for a car in normal shape. Heavy pet hair, deep stains, beach sand, or extreme buildup may need an add-on or longer booking. We quote the difference before we start, never after.
Redondo Beach, Manhattan Beach, Hermosa Beach, El Segundo, Torrance, Rancho Palos Verdes, Lomita, San Pedro, Long Beach, Del Aire, Lawndale, Hawthorne, Signal Hill, Rolling Hills, Palos Verdes Estates, and Harbor City. Just outside that line? Text us. We make exceptions for repeat clients.
We can usually fit a 90755 job within a few days, and same-week is common. Booking is a quick text or call to Patrick, you give the hillside address and what you want done, and we lock in a time and sort any gated-complex entry code before we show up.
No. As long as we can reach the car and have a driveway or apron spot on the hill, you can head out or stay inside. The truck carries its own water and quiet generator, so we don't need your hose or outlet, and we text before-and-after photos when it's done.
Yes. The hilltop gets full afternoon sun, so field dust and water spots bake onto the paint faster than down in the flats. We lift light spots with an iron-decontamination pass; etched or baked-in spots need a clay bar or one-step polish, which we'll quote before we start.
