Personally I like to scrape before gluing. I have tried different methods but scraping seems to be the easiest and most effective for me.

Thanks,
Randy

When building a kit with multiple subassemblies like a kit with an interior that need to be painted separately and then glued...do you scrape off the paint from the areas to be glued before gluing? Do you mask where the parts will joined before painting? Do you just glue the parts with paint on them and not bother to scrape or mask the contact points? Which is your preferred method?



I use them all,depend from the model (with WnW models is asking for trouble like Russ said),were,if structural etc...but if possible i prefere without paint in the joits

I try to keep joints clean, either by masking, avoiding, or if all else fails scraping. Sometimes I use a little glue on a brush to "wipe away" the paint down to bare plastic, before gluing it to another bare surface. I don't like to just flow glue into a joint trapping paint, as it creates a weaker joint.



I do the same. Itís really better to keep the joints as clean as possible, but thatís not always the easiest job to do. If itís a small part, Iíll resort to using CA or epoxy rather than regular styrene cement. There are some kits (WnW for example) where tolerances are so tight, parts must remain free of paint. In those cases, I keep a medium grit sanding ďtwigĒ and a sharp scalpel blade handy to scrape away paint. I also use a Q-tip (or a Tamiya swabó Iím not sure what they call them), soaked in a bit of lacquer thinner to remove paint from mating surfaces. I tend to build the ďmilitary miniaturesĒ way though (old school figure miniatures were generally assembled before any painting was done), where 80% of my kit is assembled, or itís assembled in sub-assemblies prior to painting. That way most significant joints are already glued before the paint goes on.

I do the same unless it is a large part; then I will scrape some away.

I mainly use Tamiya Extra Thin,I do not scrape anything as the glue will dissolve some paint anyway.I apply it carefully,and brush touch up any slight blemish,which are usually very small.
