I’m considering the Revell enamel paints, I’m assuming this will do the trick, but it is just that,…an assumption.

Hammerite?

I just use clear nail polish as it dries pretty hard. Depending on your frame colour, you might be able to find a matching colour.

Those little tins of enamel paint from model shops, they dry really hard and there’s lots of colours to choose from including metallics.

Can you get cotic green? 😀

I use car touch-up paints – e.g. Audi Brilliant Black for gloss black etc.

I use my Mrs nail varnish (on my frame that is). 😉

As you said,Revell enamel paint from a hobby shop.

Revell here, Cotic told me which code to use for their orange.

A syringe with a 27gauge needle works wonders for filling stone chips..
I use one with halfords gloss black aerosol.. Just spray into a bottle lid, suck it up with the syringe and apply.
