Using Clear Varnish over Touch Up Paint
 

I am touching up some paint work damage on the front of my Rover 75 CDTi 2005. I am using the correct "Starlight Sliver" paint, but am finding when I then paint over with clear laquer to finish it, this lifts the paint and dulls it - completely the opposite to what I had expected. Both paint and laquer came from a reputable supplier of auto paints. ED

Hi Edward.
That's odd. Are you using the correct lacquer for the paint? There could be a reaction between the paints. The other thing that is coming to mind is "Bloom" this is caused when you are spraying when its too cool and damp, the effect is like the finish has gone milky and matt.
Personally I wouldn't use a varnish as it will never be as good as the proper lacquer.

Also, are you allowing the basecoat to dry properly and are preparing it correctly before using the lacquer?

But are they the same type? For example, a cellulose type varnish will lift an acrylic type paint, especially if the paint is relatively new on.

Also is it properly keyed and cleaned? All waxes, oils and grease removed?

I've read recently from guys who spray cars for a living that there's no substitute for 2K lacquer. The companies who do repairs at your home apparently use 1K and it doesn't last as well as the proper stuff. You've obviously got another problem as has been pointed out by the good advice already given but even if you do get a decent finish you may have problems in the future with dulling or crazing

Many thanks for advice. Sorry, what is 1k or 2K lacquer? Also what comments on those companies who come to your home for small paint jobs? Edward

Hope this explains it for you Edward
