Dulling down Ford Diamond White

[w8cmp]

So OK guys - those of you who have built large scale Eagle replicas (or indeed restored the original models).

Having sprayed my 23" Eagle with Ford Diamond White I now have a beautiful gloss finish to play with.

Now this is great for decals and the like, but is a little unrealistic for the finished model. I need to add panel detailing and I'll use my pics of the original Eagle 1 at last year's convention to get an approximation of the patterns. Next will be decals on to the still gloss finish...

But my question is what you would normally use to finish the model as a final coat to dull it down a little and protect the paint / decals (if anything).

DX and Mark42 - any recommendations ??? I was thinking Microscale's matt varnish as previously suggested, but was interested in what you guys have used on your large scale models.

Cheers

Chris
