How do you avoid a crusty rim?

[Buff Orpington]

and what should you do if you get one?
My can of Army Painter Soft tone had developed a crust of dried varnish round the rim which was stopping the lid sealing. I tried scraping it off with little success. Using a bit more pressure on the lid only ended up bending the rim of the can giving me no chance of a proper seal so I've just had to decant the whole lot into a glass jar.

Always wipe it after use?

No! Not on the curtains!

She goes wild if I wipe it on the sheets.

Wipe after use with a cloth or tissue soaked in turps or thinners

Remember to always have a piece of leather handy to bite down on......

For the big crusty rim I found that issuing the groom of the stool with a wire brush dealt with it.
For army painter I use a stanley knife on the rim of the main tin when it starts to build up. The build up round the edge of the lid is usually more of a problem but will chip off. I did try using a disposable knife but the pieces of "break off" blade flying about was far too exciting!

Alternatively, rather than use the highly gloopy tinned version, invest in the excellent smaller bottled versions which are far more user friendly with less wastage. They don't harden up and prevent you opening the bottle either. They have the additional advantage of being useful during the painting process to add tone to small area and they dry quicker.

I’d agree with Tim. Only rider is, for some reason, the same colour is not the same shade between the acrylic and enamel. It’s fine, and close enough, unless you are wanting to match things exactly

Never used Army Painter washes and am not overly enamoured with their paints either. I use the Magic Wash which is not only just as good -to my mind anyway- is far more versatile and is substantially more economical.
