Painting / weathering N engine trucks with NO airbrush

Usually I use my airbrush to weather my N-scale engine trucks. However, today I do not have the energy to airbrush. Plus it's just one engine.

For those of you who don't use an airbrush to weather, how to you get a good flat finish on the plastic truck side frames to which paint and weathering powders can adhere? Brush paint a flat acrylic clear coat? Or ... ?

Thanks,

Bill McBride

I've never really had problems using Poly Scale right on trucks (if they're clean).

I know the theoretical problems, but I've never seen them.

A flat acrylic clear coat from either a brush or airbrush won't bond any better if you are talking about trucks made from a shiny slippery plastic such as Delrin.  For painting those I first use an adhesion promoter like this: 

http://www.autozone.com/paint-and-body/primer/dupli-color-clear-aerosol-adhesion-promoter-primer/460112_0_0/

Follow the manufacturer's directions, and then you can apply the topcoat however you like.

(I believe that these products work by actually etching the surface of the plastic.)

I had one truck that had adhesion problems and it was probably because I failed to wash it correctly...

Thanks, Ed.

I had used some adhesion promotor on some HO trucks and handrails a few years ago.

I was just being lazy and didn't want to have 1. clean my airbrush and/or 2. have to mask around the frames if I went with an aerosol (like the adhesion promoter).

I do have some various acrylic flat varnishes (Vallejo and Model Master) and I will give that a try, too...

You know, being lazy results in poor quality models.  :D ;) :trollface:

Ha!  But weathering can also be done well or crappy.  It takes well-done weathering job to make the trucks look really "bad"! :P
Whip out that airbrush and start spraying!  ;)

I've been using the Vallejo primer and that works pretty well.

I was going to try some Vallejo clear flat but work/life got in the way since my original query.

Which primer; the Vallejo grey surface primer?

Thanks,

For me at least,  there are too many times when being lazy ends up causing more work than not.  :facepalm:

That or the black, depending on what you're trying to copy.
