As a matter of fact I do ... and its sold on Amazon. However, finding or buying it isn't the problem. First you need to know which shade to use - flat, satin, semi gloss, etc. THEN you need to know how much of the additive to use.

I'll find the stuff and post here shortly.


Well I just did a search and now I can't find it. Give me a day or so - I'm probably not using the same search words I did last time.
