For everyday owners who want a better price when they sell
I spent 41 years getting cars ready for sale, from a car wash bay at seventeen to running vehicle preparation on a dealer lot. Here's what actually makes a car look looked-after, and what just wastes your Saturday. Watch this first:
The part nobody tells you
Look at almost any car under a petrol-station canopy or a low winter sun: fine curved scratches round the door handles, hazy patches on the bonnet, long wipe marks down the sides. Most of that was put there during washing. Grit got trapped under a sponge or a drying towel and dragged across the clear coat.
Inside it works the same way. The mess you can see is rarely the problem. What you do next is:
Get the order and the method right, and most of that never happens. That's what this manual teaches.
Swirls like these come from washing, not from driving. They're far easier to prevent than to polish out.
The least aggressive method that works
Most wasted effort, and most damage, starts with reaching for something harsh before working out what the mark actually is.
| The problem | What people usually do | What Trevor does instead |
|---|---|---|
| Dull, swirly paint | One bucket, one sponge, every panel | Two buckets, a proper mitt, top panels first, and a separate mitt for the wheels |
| Paint still feels rough after washing | Clay the whole car | Treat only the rough areas, then put protection back on |
| Stale smell in the cabin | Hang an air freshener | Find the source and dry it out. Perfume on top just gives you two smells |
| Drink spilled on a seat | Flood it with cleaner and scrub | Work out where it travelled, use as little liquid as possible, and dry it fully |
| Black, dusty alloys | Strongest wheel cleaner, on hot wheels | Cool wheels, a cleaner that suits the finish, and brushes that never touch the paint |
| Faint scratches everywhere | A full day machine-polishing | Wash and protect properly, and know when a mark is damage, not dirt |
Methods summarised from the book. Always test a product in a hidden spot first.
What's inside · 12 chapters · 178 pages
Written in plain words, with 40 diagrams, checklists and "In Plain Words" boxes. Each chapter gives you a safe working order and tells you when to stop.
The "dealer-lot standard": safe, dry, fresh and visibly cared for. Plus the small starter kit and six chemicals that cover most jobs.
How swirls really get put in, and a wash routine that takes road film off without taking years off the finish.
Tar, iron fallout, sap and water spots. How to find bonded dirt and remove only what's there.
Drying is the last cleaning stage. Avoid mineral rings, drips from mirrors and towel marks in the sun.
Wax, sealant or coating, explained without the marketing. What protection can do, and what it never will.
Dry first, wet later, top to bottom. Stop doing every interior job twice.
The film on the inside of the windscreen that makes night driving tiring, and how to remove it without streaks.
Brake dust, wheel finishes, dressings and pressure washers. How bright wheels turn cloudy, and how to avoid it.
Salt, sap, insects and damp. Let the weather and how you use the car decide the work, not the calendar.
Four questions to answer before you touch a stain, and how to find where a smell is really coming from.
Tell dirt from damage, so you stop before the last ten percent turns honest wear into obvious harm.
The pass Trevor used on sale cars: spend the next hour where the buyer's eye and wallet are most sensitive.
Who it's for
Two buckets, a proper mitt and the lower panels last. Most swirls never get a chance to start.
From the author
The book is full of short lessons learned on real cars, on tight budgets and tighter deadlines.
I've seen plenty of people clay an entire car because they found three rough patches. That's like sanding every kitchen cupboard because one handle is sticky. On the lot we clayed where customers could see and feel it, and nowhere else.
I've seen expensively coated cars covered in swirls from automatic brush washes, and cheap spray-sealed cars still looking respectable years later because they were washed gently and topped up. The habit mattered more than the price.
I've watched hours wasted chasing a smell that turned out to be one leaking shopping bag, or a damp cloth forgotten beside the spare wheel. Empty the car completely first. Then look.
Plenty of auction cars arrived with mysterious oily specks from workshop air lines. Unless you know the supply is filtered, don't aim it at clean paint. A towel and a second walk round does the job.
Look inside
No fluff and no product placement. Trevor takes no sponsors and uses no affiliate links, so every recommendation is simply what works.
About the author
I started in a car wash bay at seventeen. I finished my working life running vehicle preparation on a dealer lot, where tired trade-ins had to become clean, presentable stock on tight budgets and tighter deadlines. Along the way I prepared more than 30,000 auction cars.
On the lot, time always had a value. If two extra hours made no difference to the selling price or the customer's first impression, those hours belonged on another car. Your Saturday has a value too.
Now I'm retired, and I'd like ordinary owners to know what we knew on the lot: which jobs change what a buyer thinks, which cheap products do the work, and when to put the cloth down.
