Anyone got any tips ? :-) For some odd reason, a scuff has appeared under the boot lip of the Cerb. Just a vertical stripe about an half an inch wide and about a two inches long - a noticable indent. God knows how it got there although I did load a guitar amp into the boot in the pouring rain on Saturday night, so it could have been self inflicted. Can't think of any other way anything else could have done it. Can old repairs drop out ? I don't know. Anyway damn annoying. I've already have the paint made up from Halfords and have been rubbing away with Meguiars paint cleaner but any other tips welcomed. :-)

those measuremnts sound deep and big.

normally i build up the indent/gauge/scratch with touch up, may take days, coat after coat, relativley thickly applied until you get nearly level with the rest of the paint. i then use laquer to go over the top until it has actually exceeded the existing level of paint and is like a bubble/lump in the paint to look at.

wait for it to dry, then i wet sand the area with p2000 to bring it all level. then i go over with the machine polisher and a cutting compound/polish/wax etc. usually works wonders and better than smart repairs

But please please please test that touch up on a back edge of the door or in the bonnet as i bet my bottom dollar the match is really really poor, ive had matches from halfrauds before and they are WAY OFF. that was for normal cars not funny starmists/chameleons pearls etc so i can imagine how close their match is for those.!!

I've been looking for touch up advice for months! No smart repair places want ot touch it - mainly due to the time it takes.

The above sounds good - what laquer do you use - does that need to be applied in lots of thin layers as well?

I have a Porter Polisher but have not used it yet - bit scared to on TVR! Is it easy to screw up?

When your wet sanding how do you avoid removing the surrounding paint?

Does your repair go darker than the surrounding patches?

Pic would be great or a link to any decent guide.

I have looked on detailingworld but not found anything

Thanks for the info Shayne. I think I got the width wrong, more like 1\3 centimeter. Obviously going to have to spend more time on it then. I've not got a machine polisher but I'm off to Halfords so I could get some laquer. Yes I think the Violet from Halfords is slightly darker, sods law. I am using some Black polish on it too, but this really just slightly fills and covers up. Shame I've got the 12,000 mile service tomorrow and the Kimbolton show on Sunday. frown
Typical.

Colin.

For chips there is a product called Lanka.
Instructions go something like; apply glob of paint into the chip leaving a slight mound of paint. Allow 5 - 8 minutes depending on temperature then use a cloth with a few drop of Lanka on a block and rub gently acoss the area.

The lanka resoftens the paint and leaves a smooth surface.

I've used it for front stone chips.
It is a domestic product, I'm told there was a commercial equivalent that has been available for years.

I'm in the US, not sure if available in UK.

If you search use "NOT" fruit as well, as Lanka is another name for Jackfruitsmile

ETA it's Langka not Lanka. Sorry.

Forget the brushes and use a cocktail stick to apply the paint to the area you want to touch up. Build up layers until slightly over the original paint and then use the methods above to bring it back down to a level.

More good information that I'm sure will be useful to us all. Cheers. Just laquered it actually and don't have much time so I'm going to just try the Maguiars paint cleaner to rub it down level as a temporary fix.
