Pozdrav! It's nice to see you haven't forgot about your "other" home

I was in Rijeka just a few days ago so anytime you visit, let me know, the beer's on me...
Washing is a technique in the weathering process, basically a capillary flow of thinned out paint that gets into crevices, panel lines, around raised parts like bolts, rivets, etc creating a hard line of sort, a color limit so it accentuates details. For this you need a gloss/clear cote of some sort. Future (not sure if it's called like that any more) is a household item; a floor wax to be precise. Modelers use it because it's more economical than dedicated modeling products, it's self-leveling and can have lots of other uses like gluing really thin PE parts, polishing tiny scratches from clear parts etc, and it's good enough for decaling and washing of course.
In general, a clear cote protects your base color, as thinned out paint can dilute into your basic paint job and then everything gets either messy or even lifts up paint. To do this you need to figure out what are you dealing with i.e.;
enamel base coat = acrylic clear coat = enamel (artist oil) wash
acrylic base coat = enamel clear coat = acrylic wash... I hope you get the idea here.
gloss cote also helps to avoid silvering while decaling - air bubbles get trapped beneath the decal due to the surface roughness resulting in little white dots. When the surface is glossy it evens out the surface layer (better) so decals go on much smoother.
In the end you need to flat cote everything (that needs to be matte) and it will not obscure your painting or weathering. Let me know if I'm making sense or send me a private message and we can catch up if you get stuck somewhere...
I see Anirudh already explained about pic posting, but if you feel the kitmaker gallery is complicated, perhaps using some free picture hosting sites like photobucket, imageshack, etc is better.
I hope you post lots of photos as I'm very interested in seeing how you did your truck

Hell, send a pm anyway and let's catch up on some more talk in croatian
