Testors Dullcoat question

[Babelfish]

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 it, 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 use DullCote. I usually give it at least 8 hours before doing additional work over it, and often I'll wait overnight. I can't speak for the effect of using it over oil that has not dried, however; I use it on pieces painted with acrylics or with enamels.
It is a lacquer. I have not seen solvents like mineral spirits or isopropyl attack it. I have used washes made of oils and mineral spirits over it, with no problems to the surface below.
Hope that helps, prost!

Many thanks for your input Brad. Yes that is helpful.

Reading your reply, I think the way I phrased my initial question might have led to some confusion: I'm not wanting to apply Dullcoat over oils that have not (nor might not have) fully dried. It's the other way round: I'd be applying thinned oil washes over dry Dullcote, and am unsure what their effect might be on the Dullcote.

OK, yep, understood. Yes, I have had no problems with that combination.

Prost!

Steve:
I rarely use dullcote, especially on figures. Last time I did, it frosted a figure I'd painted in oils (I've used a heat box since). I was able to restore some of the richness of colour by using oil washes over the dullcote. Go with a light wash/glaze on a inconspicous spot and see how it looks

Hi Steve,
I used it once, had lots of faded washes on a tunic probably the best I had painted. Needed to cure some shinier bits and sprayed it with dullcote and it obliterated the lot.
Some people get on with it OK now I'm very wary and do not use it.
cheers

A once experienced something similar Richie.

I normally airbrush Dullcoat onto planes & AFVs but only right at the very end to kill off any unwanted remaining sheen, by which time the (airbrushed acrylic) paint scheme has been safely sealed in under a coat of gloss or satin varnish and the various (oil wash) weathering stages.

However on one occasion I decided to brush-paint it onto a figure that I'd base-coated in acrylics and it lifted the lot, which is how I discovered that it will kill unsealed acrylics. Lesson learned!

Stopped using Dullcote ten years ago after a number of serious issues...all of the above and more

This is by far the best available IMHO.....

Used it over oils/acrylics/metals/Zero/inks etc. etc. ...never had a problem...it takes further layers of paint or washes with absolutely no problems

Nice tip Ron, cheers. Do you decant it then put it through an airbrush, or just apply it straight out of the can?

[kagemusha]

Straight from can mate as nozzles are very good usually.

Cheers Ron ......might give this one a go ...I sprayed Testors and when fully dry it left white spots all over .....very unhappy so not used it again

Without wishing to hijack Steves great thread anyone know of a true Matt brush on ?

Happy benchtime

Stay safe

Actually a great question Kev. That would also be good to know.

I always use dullcote with no problems to date I actually prefer the spray can, usually going back to retouch anything shiny with clear gloss a brush after the dull cote dries.
