Touching up a tiny paint scar

[ProfCJJ]

I have this tiny (5mm) scar on the edge of the boot lid which clearly is down to the metal. I have some touch up paint however should I somehow treat the spot before I touch it up? Or is it too small to matter? If I do treat it what should I use?



Sorry if this sounds trivial but the paint is quite flawless and I wanted to nip this in the bud and do it properly.

Thanks for any pointers.

Op
Look for a product called kurust by hammerite.
It chemically changes rust to a sound non rust surface after you have used a fine file to remove the worst of it.
Then touch up as per normal.

Thanks! I’ll see where I can get it from.

Jenolite or Krust, will do the trick. Both easily found on Flea bay.

Plenty of how to vids on you tube. I did the bases of the sills on my daily shed last week. Be careful not to get any on fresh paint.

Could also clean up with a small file. I'd then apply rust converter (as opposed to a rust remover). The rust converters come ready to paint (i.e. work as a primer as well). Then apply your paint touch up.

Thanks all - I got some rust converter from Halfords (a tiny little bottle that will last a long time with little nicks like this!) and applied it. In a few hours I will apply the touch up paint.

Its only small but best nipped in the bud - its been irritating me since I got the car!

Cheers

Always a good idea to stop rust before covering it over with paint! So you've done it the right way round!

A stitch in time, as they say.

Looks like surface rust and not too deep. Halfords do a touch up kit that has a small course file that will get the rust off. I normally grind that back to bare metal so no brown spots show. I then apply the primer that’s in the kit, think grey for a white car, leave that for a few hours and apply a few top coats. White is really good as it blends very well. The colour match was spot on for my Sapphire black at Halfords and the touch up pen is very good as has a small bib but also thin brush to apply. Wait a week of so and then buff it down with some paint renovator and you can get it pretty good.

Have tried the rust treatments in the past and whilst they are suppose to stop rust and convert it to a stable form I have always found it comes back some 6 moths later. Only real way to stop rust totally is to remove it back to clean bright metal.

I agree with the above. I use a fibreglass pencil to get rid of the rust before rust proofing, priming and finishing with touch up. Brilliant bit of kit - removes all of the rust back to bare metal without damaging the surrounding paint.

Hi all. I have used the Halfords kit previously on other cars. In this case I used a small nail file / buffer on the scratch to make sure there were no loose bits then treated it with the kurust product. It’s now gone nice and blue and tomorrow hope to layer on some drops of paint

Agree with Wookster78. Rust converter is good but rust should be removed with a dremel or some other sort of abrasive. Only the last pits should be treated with the converter or chemical remover. Other wise it will come back.
I have been lazy with it before and been very disappointed in 6-12 months time when the paint bubble comes back even bigger.
