Now there was a learning curve I could have done without!
The last 2 hours have been spent stripping and cleaning my nice shiny new AB...why?
Copper enamel!!
How in the world are you supposed to spray metalics?
I thinned it down with Humbrol thinners, though it did not want to mix too well.
As soon as I started spraying.....wumpfff plugged AB.
My hands are covered, it took almost half a litre of celulose thinners to clean the brush and the jars.
Lacquer thinner vapour now fills the basement, I have windows open, fans blowing..trying to evacuate the fumes.
Before I started, I searched the forums for any tips, could not see anything so assumed it was all as normal, should have realised that the flakes would block the AB,but still.
So, can I spray metalic copper? or am I reigned to brushing the hull bottom?

Don't mix medias-weren't you spraying enamels , or acrylics yesterday? My advice-use a rattle can for lacquer or metallics. :-)

Lower the pressure. That will allow you to pull the needle farther back to get the same volume of paint flow, thus opening the nozzle a little bit more. Some metallics are difficult to find the right combination for but they usually work fine.

I only ever and allways will use enamels, apart from when I do the black around the stern area, but that will be brushed.
Only thing going through the AB is enamel...ever.

Should the metallic mix ok with the thinners? as quick as I stirred it settled onto the bottom of the jar.
I'll see if I can't pick up a rattle can for the copper/bronze

Vapo-I use a rattle can for lacquers and metallics- much easier, and keep those metallics "well-shaken"-you how quickly they settle. Sorry about the mixed-media mix up-I had you mixed up with someone else.

PS-I keep large cans of common colours on hand from the hardware store (flat white, black, red, yellow and aluminum, etc.).

I think that learning how to manage enamel-thinner-pressure- nozzle aperture will be harder than with acrylic, peculiarly with metallic pigments as they are huger; but go on, you get it with patience. An alternative could be Gunze metallics or Alclad; with this latter choice, the trick is in the undercoat (priming ). If I remember well, I sprayed Alclad chrome with a 0.15 Evolution without problems. Take your time and make experiences.

Thank you all for coming José

Thank god for marshals on a Sunday! lol Two cans of testers copper metallic, hull bottom drying now.
I fully intend to get to grips with the finer points of ABing, just not on this kit.
I also picked up a tub of acrylic matt black for the intricate work on the back end, already dislike it, it won't stick like enamel, I guess I need to put the model in the dishwasher first,lol

So I painted the hull bottom with the testers copper, let it dry, I also painted a bit of scrap plastic as a test bed. Well the copper comes right off when you use a masking tape. So I sprayed the test piece with dull coat, let it dry, and it still comes off with the tape.
What in the world can I do to protect the copper but allow mw to mask it so I can paint the rest of the hull?

I have heard somewhere of using post it sheets as it has a very weak tack and also damp paper ( I think the second one was on http://www.largescaleplanes.com )
Used neither of them personally, now I am experimenting with Micromark Mask it easy mixed with pink acrylic, and a surgeon scalpel, but I think it won't suit your needs.

yeh, I just read about the wet newspaper one, I may also try the parafilm, but the surface is very detailed and I really don't want any colour bleed?
I'll do the dullcoat Wednesday after the copper has cured properly.

I've seen a trick in a Kalmbach book (how to use an airbrush ? ) and I had seen the article on one issue. It was about a street car painted in white and yellow. When the white coat was dry, the guy put Tamiya mask AND a clear coat to seal it, then he sprayed the yellow color : chapeau bas, Monsieur, it was very clever.
An alternative if you have intricated detail is liquid mask. I think they are not identical as far as tack is concerned, so trial and error is the rule; apart from the model dedicated range ( Microscale, Micromark, Humbrol, etc...) there is also the drawing gum used in fine arts and some people even use molding latex as a mask, so you can see that your choice is rather wide. You mentioned a clear coat : it could help, but are you sure that you need a dull coat ?

what else can I put over metallic copper? the dullcoat is take the shine out of the metallic and protect it at the same time.

If you want to take the shine out, it is okay; that is what I meant : do you want to take the shine out ? I think you should look at Model Masters Metalizers or Gunze Metals as it could widen your choice.
