Chipped the back door. 1mm. color code 25D
how do i restore this? search on chatgpt and they told me the following thing. help me.
1. Touch-up paint (most important)
If your paint code turns out to be A4D Arctic White, I’d buy the genuine Mazda paint.
Best choice:
Or you can get the genuine Mazda kit from a Mazda dealer such as Crayford Mazda Accessories for around £14.
If you haven’t confirmed the paint code yet, don’t order the paint just yet. First check the sticker in the driver’s door shut.
2. Isopropyl alcohol (IPA)
You’ll use this to remove wax, dirt and grease.
Around £5–8.
3. Microfibre cloth
Around £2–3.
4. Cocktail sticks
Yes, ordinary wooden cocktail sticks.
Around £1.
The cocktail stick gives much more control than the brush that comes with the paint.
Total cost
Touch-up paint: £13–14
IPA: £6
Cloth: £2
Cocktail sticks: £1
Total: about £22.
That’s enough supplies for years of stone chips.
Step-by-step repair
Step 1 – Wash
Wash the area with car shampoo.
Dry completely.
Step 2 – Remove the red transfer
The red marks in your photo look like paint from the bin.
Put a little IPA on a microfiber cloth.
Rub gently.
If it doesn’t come off, don’t force it.
Step 3 – Clean the chip
Put a little IPA on the end of a cocktail stick or microfiber cloth.
Clean inside the chip.
Wait 5 minutes.
Step 4 – Shake the paint
Shake the bottle for 2–3 minutes. Mazda paint pigments settle quickly, and thorough mixing helps the colour match.
Step 5 – Don’t use the brush
Unscrew the bottle.
Dip the tip of the cocktail stick into the paint.
You only want a tiny droplet.
Step 6 – Fill the chip
Touch the paint into the centre of the chip.
Don’t brush.
Don’t smear.
Just let the paint flow off the cocktail stick.
You should still be able to see the edges of the chip.
If it looks like a blob, you’ve used too much.
Step 7 – Let it dry
Leave it for 20–30 minutes (or follow the instructions on the paint).
Do not touch it.
Step 8 – Second coat
Look closely.
If the chip has sunk below the surrounding paint, repeat the process.
Usually 2–3 thin coats are enough.
Step 9 – Leave it alone
After the final coat:
don’t wash the car for about a week
don’t polish it
don’t wax it
Let it fully harden.
Things NOT to do
❌ Don’t sand it.
❌ Don’t use a cotton bud.
❌ Don’t paint outside the chip.
❌ Don’t use one thick coat.
❌ Don’t polish immediately afterwards.
One extra tip for your specific chip
Your chip is on the sharp edge of the rear door. Gravity will try to pull the paint down the edge.
When applying the paint:
Hold the door closed.
Apply one tiny drop.
Wait about 30 seconds to make sure it isn’t running before adding any more.
That will give you the cleanest result.
Before you buy the paint…
Can you check the sticker in the driver’s door jamb and send me a photo? I want to confirm whether your CX-30 is A4D Arctic White or 25D Snowflake White Pearl, because using the wrong white will be noticeable even on a tiny chip.
