project: Honda RA272 #1

I started with the engine components of the Honda RA272.  The molds are dated 1996, so it is not one of Tamiya's more current kits.  However, the quality and detail of each component is pretty impressive.  It did not require a lot of sanding or prep before laying down my first coat of primer.

I use Tamiya grey surface primer that comes in a 180ml aerosol can.  It lays down very easily, thinly, and drys to the touch within minutes.  I was able to find it at a local hobby shop, but I found that supply is very limited from Tamiya.  Other tools needed for this step include an X-acto knife, flat cutting shear, and I used a 1000 grit sand paper from Home Depot to finish the edges of the parts where needed.

The grey primer is difficult to cover if you are painting a opaque light colored paint like white.  So if this is the case, apply the primer thinly.  For darker colors, the grey primer will be hidden well.  I've learned that it is not uncommon to apply a layer of white primer on top of the fine grey primer or a mist coat of paint for lighter color coats.  I found that it is not necessary most of the time and the thin layer of grey does the job in defining surface imperfections and providing enough bite for your first color mist layer to grab on to.
