what should I apply after the base coat (acry) and before the decals?, after the decals and before the weathering, gloss, clear, satin etc etc? and what brands do you recommand.
thanks.

Vallejo gloss

Personally I'd use either Vallejo Satin Varnish or Future .

Tamiya or Gunze gloss varnishes. Gunze maybe is a little bit finer

thanks guys, so I give the model a gloss coat only in the areas that the decals will be applied? and then a coat of matt, and what next? I mean what should I use to protect the base coat when starting with enamel weathering

Hej Jamal. As you have an acrylic base, you dont have to lay a gloss coat before weathering with enamels. But you should still test to check your thinner is not too hot, so that it lifts the acrylics. I use Humbrols own enamel thinner and this isn´t a problem.
If you are going to lay gloss before decals, I suggest you spray the whole vehicle as the base coat will get darker where the gloss is. I usually spray gloss coat again after decals. Helps hide the carrier and give the decals the painted on look. I use future for gloss coats.

Well, there are differents thinking about

Someone applies the gloss only in the decals area, someone else on the whole model. If you were an aircraft modeller you'd paint on the whole model, but aircraft modellers on average don't weather their models heavily.
Both methods have pros and cons.
Applying the gloss only in the decal area is faster and allows you to reduce the paint thickness, on the other hand, base color tends to darken under a coat of gloss varnish so you could have some darker stains. Of course this flaw could be most visible on the lighter colors but you have also to consider that after doing washing and filters these stains would be little visible. Applying a coat of gloss varnish on the whole model, allows to have a homogeneous color, but you have to spend more time and, as I told you before, increases the paint thickness. So the answer is....it depends. Personally I apply the gloss only in the decal areas just when I have small markings or darker colors, but i think that a coat on the entire model is the safer method
Regarding your second question, well filters and washing have to be done on SATIN or GLOSS surfaces. Matt coat has to be the last step in your coloration process
So more or less the steps are:

1 Primer
2 base color
3 First gloss coat (on the entire model or just in decals area)
4 decal application (with decal fixer and decal softner and cutting the trasparent film as much as possible)
5 Satin or gloss coat
6 Filter and washing
7 Matt (or satin) final coat

These are my opinions anyway. In the site there will be a lot of guys who will be able to explain you in a better way (and maybe they will be able to correct me)

cheers

thanks Frank and Mauro

Jamal, check out the "Finishing and Weathering Sequence" thread at the top of this forum. It will answer all.

A coat of gloss smooths out the paint so that the decal silvering is eliminated. I've used many brands and nothing works better for a smooth gloss finish then Testors Model Master Glosscoat. It's a lacquer based product, so it dries fast and rock hard.

After decaling I apply a 2nd and maybe a 3rd coat of gloss to blend the decals in. Then weather. Finally, a coat of Model Master Dullcoat finishes the project.

I've used Pledge with Future, but found that air brushed it doesn't give you as smooth as surface as the Glosscoat, and hand brushed puddling becomes a problem. I do use it for small sub assemblies though.
