I have my way of working but I'm not always satisfied with it so I want to know what's your way of working?
my question:
when I glue my work on a backer and then finish it with glossy lacker the areas along the glued parts and the corners never get enough lacker and keep dull.
so instead I sometimes finish my work before I glue it together.
But then I have the feeling that the "contact glue" isn't that good as the wood glue and on some little spots I see the glue coming out.
removing it wrecks the lacker finish so I have to spray again and the problem is back to the beginning of my question..... 8) ::)
so who do you guys and gals work,
glue first or finish lacker first?

I do the glue up first. When I spray, I tilt the piece and spray a light coat in 4 different directions. I use a piece of brown paper in between coats and do it all over again. That usually gets all the cuts finished.

You could spray a bit of lacquer on a non porous surface (i.e. the inside of the cap) and use a small paint brush to touch up the corners. Likewise if you use wood glue after the lacquer and you see squeeze out glue, use a small damp brush to remove it while it is still wet.

Marcellarius, I do a lot of what I call "laminate work" or a thin cut out glued to a backer. I have found the same problems with it. I always lacker first. then glue. But what I do since contact or wood glue doesnt work well on a lackered finish is actually use super glue. I get it cheaper at the Dollar store and once I apply the glue I simply hold it in place for a minute. Hope this helps.

Doing detailed portraits makes it impossible to spray after gluing so I do the lacquer spray first, touch up sand with the paper bag and then take Alene's Tacky glue, squeeze some into a plastic lid and use an artist paintbrush to apply the glue to the back of the piece I am gluing. Once I have the glue on in sufficient amount and in enough places I feel it will hold I put the piece on the backer, put a sheet of 1/2" plywood over the face and set a gallon can of paint on top for a couple hours. I have never had a piece separate.

I do exactly as Julie!

What I do when I have a piece with a backer is glue it and make sure all the excess is wiped off with damp paper towel. after it dries and when I am ready to coat it I attach a command strip hook to the back of the project and using wire I hang it from a piece of 2x2 stretched across saw horses and spray. After it dries I remove the command strip and TA TA DAAAAAH. No muss no fuss.
I just acquired a 3 hook hanger. The type you hang over the back of your door. FREE what can I say?

Depending on the piece, I may use the paint points but I also use and old lazy susan from a yard sale. Just spin to spray all sides

thank you all for the information,
with some small inner cuts (some smaller then 1/16") I find the brush not suitable.
especially not in pointy corners.
but spray doesn't do well there either.
maybe I should switch from glossy to semi gloss, this way it's not that clearly visible that it's not shiny in the corner.
thanks again!

I have never heard of using brown paper. How is it used and how do you do it?

Brown paper - I keep a roll of brown paper in the shop (available in any paint department) to put under projects, make templates and yes, sand with. It works like a very fine grit sandpaper. Spray finishes leave a little rough from very small air bubbles in the finish. A quick buff with brown paper and they are smooth as a baby's butt.
-
I use cardboard from around the house under projects. Cereal boxes, soda boxes etc. My brow paper comes from the grocery store.

Wow thanks for that Julie, I had never heard of using brown paper before for standing. I have a large roll in the kitchen cupboard that never gets used, it will now.

Brown paper is like 600 grit sand paper.
