discussion Superglue and painted parts

[Guest]

I need to glue the tiny landing gear parts for my 1/72 Lancaster. The areas to be glued together are less than a mm across and already have paint (Acrylic, Vallejo Air) on those areas.



== I think I read some where that Superglue can join painted parts. Is that true?



If so which glue brand? The parts are very small and light and it would be difficult to hold them together for more than a very few seconds without movement. Therefore I think I need a fairly fast-setting version (but probably not a gap-filling type). John sells for plastic (that is, not clear parts):

Red bottle

Roket Hot: Super-thin, fast, penetrating adhesive; sets in 1-2 seconds (but 1-5 secs on the deluxe materials site).



I find his listing difficult to understand and the deluxe materials site lists the red bottle as having the shortest setting time: 1-5 secs.



== Is that the one I should go for, for my landing gear?



Thanks.

You can get something called kicker. You use your CA as normal, place the part where it needs to be and give it a quick squirt of kicker and the CA will cure in the blink of an eye. Can be very useful at times.

I Often use CA to fit parts after they are painted. Any CA will stick any paint. But remember you are only glueing the paint together. So its not a structural bond. It the paint lets go so the part will fall off. With the paint.

I would advice as far as possible scrapping the paint off with a sharp scalpel and going by the old proverb: Less is more. ie. the less CA you use, the quicker it will cure. In fact to much and you can have a heck of a job getting the stuff to stick at all.

Ditto to what Ian has said, the only thing I do different is I use a bottle of Kicker rather than a spray to give me more control with a brush.

Ian, forgive me, but may I ask what CA is please...

Cyanoacrylate. Superglue. Its a type of fast-acting glue which sets quickly (in seconds) only when the two parts are pressed together (and how that works beats me). It can fill gaps, or when thin can act like the conventional plastic cement, only faster setting. I believe that it sets very hard after a few hours and can make sanding plastic parts glued with it difficult due to the difference in hardness.

Thanks. I think I will just scrape off the paint.

It's the lazy way of writing super glue. Lol
