Acrylic vs. Enamel Paint for Plastic Model Building Kits?? - Model Railroader Magazine

Jeff,

  This topic has been discussed extensively several times on the rec.models.railroad Usenet list, although not in the recent past (which means it's probably due to come up again any time soon...)

  Lots of folks like to use acrylic craft paints for buildings and scenery because they're inexpensive, easy to use, come in many different colors, and give the nice flat finish you want for those uses.  A few individuals have even used them for rolling stock, so thinning and airbrushing them has also been discussed on R.M.R.

  Delta's Ceramcoat seems to be a widely-available and well-liked brand and is often mentioned in those R.M.R discussions.  If you search the list for that name you'll get lots if hits.  And if your Internet provider doesn't give you Usenet access (sadly, that's becoming more common) you can always reach R.M.R. through Google and do your search there:   
 

HTH,
Steve

P.S.  Those DPM kits can look great with a light coat of red oxide primer out of a spray can (Krylon or whatever's available).  Then do the trim and some dry-brushed weathering with Ceramcoat and you'll have a very respectable looking building!
