Restoring Sun-Fried Trim and Chrome

Red dust, creek crossings, and corrugated roads don't just test your 4WD—they test your cleaning game. Most people get it wrong.

A no-nonsense checklist for bringing faded plastics and pitted chrome back to life. Perfect for cleaning up the rig after a dusty summer trip or a stint at the beach.

Restoring Sun-Fried Trim and Chrome

Aussie Conditions

Aussie red dust is iron-rich and bonds to paint. A regular rinse won't cut it—you need proper pre-wash and pH-neutral soap to avoid scratching.
Quick Summary

Look, the Aussie summer is absolutely brutal on trim. Between the 40 degree heat in the shade and that fine red dust that gets into everything, your plastics will turn grey faster than you can say 'no dramas'. This guide is a quick checklist to help you get that factory look back without wasting a whole Saturday. I've done this on enough old LandCruisers to know what actually works and what's just marketing fluff.

01

Summer Realities

I learned this the hard way when I left a black Patrol out in the Broome sun for a week, if you don't treat the trim, it doesn't just fade, it actually starts to crack. Don't bother with those cheap 'back to black' sprays from the servo; they're mostly oily rubbish that'll wash off the first time it rains. You want stuff that actually bonds to the surface.
02

The Right Gear (Don't Skimp Here)

What You'll Need

0/9
Dedicated Trim Cleaner — Something like Bowden's Own Agent Orange works a treat on red dust.
Quality Trim Restorer — Gtechniq C4 is my go-to. It's pricey but lasts a year, not a week.
Chrome Polish — Autoglym Metal Polish is a classic for a reason.
Microfibre Applicator Pads — Grab a 5-pack, you'll go through them.
Soft Bristle Detailing Brush — Essential for getting dust out of the grain.
Masking Tape (Green or Blue) — To protect your paint while you're scrubbing the trim.
Isopropyl Alcohol (IPA) Wipe — A 50/50 mix with water to strip old oils.
Fine Grade Steel Wool (0000) — ONLY for heavy pitting on real metal chrome, keep it away from plastic!
Nitril Gloves — Some of these restorers are nasty on the skin.

Before You Crack a Tinny

What You'll Need

0/4
Is the surface cool? — If you can't keep your hand on the plastic, it's too hot to work on.
Are you in the shade? — Working in direct 2pm sun is a recipe for streaks and frustration.
Have you washed the car? — Never touch trim until the loose grit and salt spray is gone.
Is it real chrome or plastic? — The 'flick test', if it sounds hollow and plasticky, don't use the steel wool!

The Game Plan

Tap each step to mark complete
01

Deep Clean

Spray your cleaner onto the brush and scrub the plastic trim in circular motions. You'll be amazed at the brown muck (and red dust) that comes out.

02

Tape Up

Run masking tape along the paint edges next to the trim. I once stained the white paint on a HiLux with trim restorer, absolute nightmare to get off.

03

Decontaminate Chrome

For real metal, use the polish and a cloth. If it's got salt pitting, use the 0000 steel wool very gently with plenty of lubricant (even soapy water).

04

Strip the Surface

Wipe all plastic and chrome with your IPA mix. This removes any leftover soaps or waxes so your restorer actually sticks properly.

05

Apply Restorer

Put a few drops of restorer on your applicator. Work it into the plastic in small sections. Less is more here, don't go nuts.

06

Level it Out

After a minute or two, lightly buff the trim with a clean microfibre to ensure an even finish. This prevents that 'greasy' look I hate.

07

Cure Time

Let it sit. Most good coatings need at least 12 hours to cure before they get wet. Check the weather for storms!

05

Final Inspection

What You'll Need

0/3
Check for high spots — Look at the trim from an angle to see if any areas look darker or patchier.
Check the gaps — Make sure no white polish residue is stuck in the cracks near the headlights.
Peel the tape — Pull it back at a sharp angle to avoid leaving adhesive behind on the warm paint.

A Few Hard Truths

Honestly, if your trim has turned chalky white and started 'pinking', it's probably cooked. No restorer can fix dead plastic. In that case, you're better off looking at a trim paint or just replacing the piece. Also, never use tyre shine on your interior dash, the glare off the windscreen is dangerous in the Aussie sun, and it'll crack the vinyl eventually anyway.

Watch Out

Avoid getting trim restorer on your glass; it's a massive pain to remove once it cures. Also, keep the 0000 steel wool away from 'chrome-look' plastic (like on modern grilles) or you'll scratch the silver coating straight off.
