For three years I've used Humbrol varnish from a rattle can, and I've never been 100% satisfied with the finish Ive achieved.
This week, when adding what I was hoping would be the finishing touches to my latest, I have virtually ruined (in my eyes) a model I have spent a couple of months working on.
In my opinion, purely from using this **************** varnish. Clogged nozzles, uneven finish,drips,,just about everything has hit me with this model. In fact, its been a jostle from start to finish.
Anyway, I digress.
The Humbrol rattlecans have been consigned to the bin. I swear I will never use them again. No fault of Humbrol etc, I just dont personally get along with them.
I purchased some Windsor + Newton Varnish but havent tried it on a model yet, just a test piece.
So my question is

What Varnish Do You Use?

Well Nige ,sorry to hear about the downs of your project . I use a few different ones , Testors dullcote in can as well as bottle . Microscale -micro flat can be brush painted or airbrushed . For airbrushing you can diulte it with water and cleans up in a snap .
I have never had any issues with these two brands . So that's what I use .

NIge I use a varnish called Delta Ceramcoat. It is a waterbased Varnish that comes in three Sheens.



Matte, Satin, and Gloss.

It cleans up with water, no smell what so ever, dries in 10 minutes, can be used straight out of the bottle and sprays nicely. You may need to add a drop or 2 of extender for the short dry time. Doesn't yellow at all.

Hope this helps

I have to use what I find, so right now I'm using Model Master clear and flat coat. It works ok, as I see it, but the flat tends to build up on the needle of my Badger. I haven't dared mix that with water, so I use alcohol and mix really thin.

Only real problem I have, but I guess that goes with the territory when you shoot from an airbrush, is that it's really hard to see the spray, so I go hard and fast . That way the spray is more visible.

Hi
I use Xtracrylix matt & satin thinned with water in the airbrush & get some great results.

I think i've tried most of them and Gunze H20 works the best by far for me. Well for flat clear anyway- it actually ends up with the slightest sheen instead of dead flat, but looks right to me.

But if rattle cans are your thing, Tamiya expanded their TS ranges recently to include Flat and Semi Gloss clear laquers to join with their long available Gloss clear. I've tried both their new clear laquers and they're excellent. Just a question of whether you deal in laquer based paints or not and if you can get them where you live.

I use either Windor & Newton or Dahler artists varnish in gloss and flat (brush on)- it's an acrylic varnish; or Valejo flat in a rattle can for a top coat only. The artists varnish doesn't yellow over time, but the 'flat' version actually gives a slight sheen that looks good on aircraft.

Thanks for the replies everyone.
I am definately looking to airbrush varnish from now on. The only time I intend to use a rattlecan for anything in the future is primer.
I have some Windsor + Newton and I've ordered a bottle of Testors Dullcote so I will give those two a try first.

Terri.
Do you thin Testors Dullcote or does it spray direct from the bottle ok?

Thanks again everyone.
Nige.

Nigel , It all depends what I'm painting . For small parts or areas I use it straight from the bottle . When larger areas need this I thin it with thinner ( 60%thinner ) .It's to thick to spray from the bottle . I also always have a small cap full of clean thinner and q-tips so when glogging happens dip q-tip in thinner and clean the nozzle .
