Clear coating chrome like Green Stuff Chrome Metal

[Mattwurst79]

Hello everyone,

I have a question on how you guys clear coat painted Metal like Chrome oder so.
I have for example Chrome metal from green Stuff which is absolutely awesome but when I try to clear coat the model after Assembly the Chrome colors will not take the clear Coat paint it is like you Spray water on polished Metal creating bubbles.
How do you do that?

Most clear coats will dull chrome .

The clear is beading up on the chrome ?
Which clear coat ?

I've never used any paints from Green Stuff .
Which chrome product are you using ? --> https://www.greenstuffworld.com/en/search?controller=search&s=chrome

I use the chrome metal paint from your link.
Maybe it is i am using mostly water based clear coats.
Maybe i should try alcohol based like Tamiya?
Just came to my mind while we were chatting

I just checked all my clear coats are waterbased. Vallejo and Mig.
They pearl on a glossy surface especially on chrome paints since their surface is very smooth

Are you thinning it ?
over thinning it with water ?

Is it necessary to clear-coat the chrome paint at all?

Yeas, the chromes take fingerprints so easy and also there is no way not to clearcoat them when you coat the model omitting the chrome areas. For example the lower belly of an airliner in chrome or the leading edges of the wings are very often chrome while the top is white. But when you spray over the model to e.g. seal the decals which are sometimes also on the chrome area you have to clear-coat everything

I think these are like Mr color metal colors, clearcoat is not really recommended, the mr color has a wax like ingredient which allows it to be buffed to a high shine but will rub off on your fingers when handled, I have got clearcoat on the mr hobby but it with make it look just like silver paint.

LIke the AK True Metal ?

Wax is going to make it un-coatable

Thinning with water

Use a water based acrylic thinner for the clear , as little as necessary to airbrush .
I never thin clears .
Vallejo's AB thinner is good .
The thinner is water but with a propylene glycol retarder and a tiny amount of ammonia as a surfactant

You can over thin it with water , or thinner -- it will eventually be like spraying water and will bead up .


I looked at that chrome paint .
It looks like a solvent acrylic since it's alcohol base . not a nitrocellulose lacquer . -- or anything with wax in it .
It shouldn't cause any issues with clear coat adhesion .
I think you are over thinning the clear .
I've never heard of anyone having this issue with Vallejo or MiG clear coats .

Just keep in mind that clear coats will dull the chrome effect away .

The clears i have need to be thinned. They are too thick.
I will try to thin least possible now.
Maybe other modelers add the chrome paint after the rest of the model was clear-coated as the very last step? Dont know...
