Actually a couple of questions ...

1) How long before it is FULLY & RELIABLY dry following application? Hours? Days? Weeks?

2) Will thinned oil washes attack it and lift it off?

Asking because when I use Dullcoat, it's usually my very last job on a model, so complete drying time is not an issue. Only this time I want to dull down an unwanted sheen in the acrylic base coat before carrying on (to save having to mask off again and repaint).

Thanks for any tips!

I've used Dullcoat, exclusively, for all my modeling needs for as long that I can recall...40 plus years maybe. I let it dry no less than 24 hours after application. In short, for me, it "seals" the entire paint job for the weathering process. It has never lifted away from the model, separated, discolored, clouded up, or changed the hue of the paint. It will take a light wash...emphasis on the word 'light' using any medium. I will use mineral spirit (never turpentine or paint thinner) to thin artist oils, but in micro applications: never heavy or alot. Water based weathering is a plus as well. Weathering is at its best when they say 'less is more'. My 2 cent.

I've been using it for 40+ years also. It's about as simple to use as anything else you'll find. It's a lacquer so it dries fast and I usually wait 24 hours to before mucking with it. I make sure the paint is dry before using it, 2-3 days. Thin coats are key.

Ditto on the replies. Using it for mucho decades. Sad that it might be disappearing. Hope I am wrong and will be sternly corrected
