I looked in the Advice forum but could not find a previous topic on this. SO, since I had a question, I thought why not start a new one.

I am going to be starting on a new projuect and will be adding a detail set. THe base kit is a Trumpet KV1 with the add on being from Lion Roar.

I have cutting/holding tools already. But, what to I use for glue? I had always used a supe glue in the past, but I have not ever worked with brass parts.

On the finish side, will just about any paint stick to the brass parts? I normally do not primer and kits before the base coat, should I primer everything or not?

Thanks in advance!

be sure to clean any metal parts. Superglue or Epoxy are the most economical options for attaching PE and other metal parts.

I almost always airbrush a coat of Floquil primer on metal parts. That way I can use any type of paint over it. Depending on what your doing and how big the parts are it may be easier to prime them first and scrape the primer off the areas to be glued.

I tried using acrylic paint over brass and it didn't stick. It may have been the type of paint I was using.

Clean everything prior to bonding (isopropyl alcohol is very good at getting off grease and dirt.

Lightly abrade the surfaces to be bonded. Scuff with scotchbrite or 400+ grit.

Superglue is good abnd fast, but has low shear strength (just like on plastic).

Epoxy bonds better and is tougher, but is hard to apply as cleanly and items must be set aside for much longer until the bond kicks in.

Priming everything after bonding is a great way to get an even and well bonded paint job. I also find Floquil to be a really good primer for models that adheres well to plastic and metal and doesn't obscure fine details.
