Re: Sealing photo-etch

Just depends what you are trying to do? Photo-etch is a bit different to work with and requires different prep work if you want to do it right? If you want to retain the natural brass finish(I've never done that),you would need to give it a lite sanding on its surfaces, bend it to shape(if required)...

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.
