Gluing before painting or Visa Versa

[DaveBaxt]

Where ever I can I have always glued before painting but never get that perfect line between two different colours or colour on wood. Its ok when it is possible to use specialist tapes to get lines on large areas. However I find it very difficult to get neat edges when  glueing intricate parts. Therefore my question is can you paint the objects first and then glue them onto an area already painted with acrylic and if so will it hold? Is it neccessary to remove an area of paint or leave off part of the paint to get a good wood/metal to wood hold? Than you  Dave

Morning Dave, as a general rule paint and glue are not good friends. The paint acts as a barrier often and the glue has nothing to adhere or fuse into, to make a bond. Also some glues will eat into paints and cause them to wrinkle (though that is more a problem for plastic and weld type glues.)

So your initial comments are correct, glue before paint where you can and mask everything else where you can’t (unless you have a a really steady hand - I don’t ☹️)

 I often paint small parts first, then have to scrape the paint off in the contact surfaces to apply to a model. Hard work sometimes and yes I often (okay very often) have to do local “touch-up” painting. 
You are not alone in this Dave, but it just one of the little challenges of model making, really don’t think that there is a short cut.

Thank you once again for your help and quick reply. Andrew It looks like I will have to carry on as I am then. Unfortunately I too have not got a very steady hand and have to mask about everything I possibly can and if not you can usually tell. There are many exsamples of absolutely fantastic painting and just wonder how they manage such great paint jobs. I suppose it just down to very good workmanship so will probably just have to perservere and everything seems to be less is more. .
