Re: Fixing panel line messes

I've used 5 minute steel epoxy instead of regular body fillers. Almost the same deal as using a super glue filler, but a "stronger bind" I.M.O and its not hard to scribe and it stakes tooling pretty well and just as easy to prime.

Re: Sealing photo-etch

I am guessing that you have painted the photo etch and you are intending to put decals on it?I don't think you will have much luck just putting your decals directly on bare photo etched brass.So, if that is what you are doing,I'd at least give the photo-etch a light sanding, paint it(give it a gloss...

Re: polishing Clear resin?

I actually don't know if you can polish clear urethane resin or printed resin or not?I'd say,Dremel has some soft polishing bits I'd gather.....not sure if a regular plastic polishing compound will work or not?Maybe try experimenting on either scrap or non essential areas on the kit??

No idea.Depends what kind of paint it is,but typically paint manufactures suggest that you don't mix their paints with a different manufacturer's paint.

I have a similar issue coming up.I have a 1/4 scale resin figure and the character is covered in tattoos.However,as expensive as the kit was,no decals come with it.I'm not sure how to go about finding the correct tattoo images,printing and scaling them correctly let alone having them "made".

atomize metal powders

Has anyone attempted to work with "atomized metal powders" in painting/finishing a kit(of any kind) in a medium (airbrushed or brush painted) to achieve a more realistic metal/metallic look on the model?
