Anyone done official touch up before? Help me?

[aaronon]

Hey!

So there is a wee rusting stone chip on my bonnet. Really small but I'm afraid of it developing so I bought the official touch up paint.

Is "Nimbus grey" also called "Pepper grey"? As I have nimbus but the box says pepper. There's no instructions with the paint either so I'm confused. Can anyone tell me what to do?

Should I use a tooth pick to drop on the paint... And push it right in with my finger..... Then leave it and scrape bits off with my nail that dried on top (outside of the crater?).

Then put on the laquer? Help would be much appreciated :)

I would, get rid of any rust with a tiny bit of 800 W&D (WET), then apply a touch of zinc primer with a tiny soft brush, leave it for an hour, light sand with 1200 W&D (WET), then apply the colour with a tiny brush. Leave it overnight, then flat lightly with 1200 W&D (WET), then apply a coat of laquer (brush), leave again overnight in a dry place. Then flat again with 1500/2000 W&D, then cut & polish the area.

This is how I would do it. If none of that makes sense, get someone else to do it. Because it honestly sounds like you haven't got a clue about paintwork.

Thanks for the info.

Checked that site out.... Sweet baby Jesus SANDPAPER?!?!?

[jammydodger]

It's wet dry sand paper which is finer than normal sand paper and is usually polishable, even with the G3

I'm scared hahaha! I see that IPA alcohol is used to prep in order to make sure the paint isn't just going on wax. I've searched halfords for alcohol but can't find anything. Do you know of another name for it? I'd need to buy it in a shop.

There's some in maplins. Maybe spray it onto a cotton but and ten vigorously wipe my rusty chip hole before painting?

Does the paint need to be level with the old paint when filled in.... Or should you leave a bit of room for the laquer which then boosts it to one level? :S

You are right with the Pepper Grey paint you have for a Nimbus Polo

The VW paint shop guys call it Pepper Grey as that's what it's called outside of the UK
and how it's named on the VW supplied paint

There is also a Nimbus Audi colour but that's Pearlescent and ours is Metallic

I buy the rattle cans for touch up because it's thinner and not as blobby
you can spray a little in a cap or lid and let it thicken up ready to use and apply the thinner paint

I use a tooth pick or sharpen a match and dab a few coats on like a marker pen, drying off in-between
and the tooth pick lets you work it into a sharp corner

Polish off the 'over done' paint on the original paintwork before building the level up with the clear coat
Take your time and let everything dry well before the next stage

Don't go near a stone chip with wet n' dry paper ~ you will only make it the size of a finger nail

IPA is Isopropyl Alcohol and not Greene Kings India Pale Ale

Sorry Nigel, but you are wrong.

Firstly, you need to remove any rust built up in the hole. Don't go mad, just use a tiny piece of 800 grade, to kind of dig out the hole.

You also need to flat the dried/hardened paint. with very fine W&D, to get it the same level as the original paint. YES it will look like you have now got a bigger mark, immediately after rubbing, but once you cut and polish it, the shine will return. After touching up use 2000 grade paper, no bigger than you need to cover the new paint, this will then blend your new paint with the old surface. Use it WET with plenty of clean soapy water.

But you must use some fine cutting paste and polish to bring it back to a shine. Halfords used to do rubbing compound in an aerosol, which was super fine and ideal for this.
