Re: preparation of styrene kits for painting

The EPA made the company doing the Statue of Liberty use Baking soda. Of course you can buy Aluminum Oxide because it is used for things other than blasting but they do not come into your home and stop you from hurting yourself. I talk to the company that did our condo ( because I am a director on the board) It can not be used by them. The directives are out there from the EPA.

Larry,

When was the EPA rule? My wife is a glass artist and still gets
aluminum oxide for her blasting?

EPA will not allow the use of the Aluminum Oxide any more. The Statue
of Liberty was done with Baking soda. The work done on our walks in
our condo assoc. was also done with baking soda.

Doug,

This is one of those topics that everyone will have a slightly
differing opinion and approach.

I routinely grit blast my resin models, wash them and let them air
dry before spraying a grey primer on them. For plastic kits, if I've
made a lot of modifications (i.e. filled holes, added rivets,
removed
rivets, repair surface defects, etc.) I still usually give these
cars
a light grit blasting; if it is a car that really didn't require
those types of modifications, I have been wiping them down with a
cotton ball soaked in isopropyl alcohol; I then let the car air dry,
and apply a grey paint to them. I think the grey paint will give
your finish coat a better "color."

Regardless, I always grit blast the plastic trucks; you can mask
off the holes for the axles, or otherwise plug them to prevent the
grit from getting in there; I usually just blast the truck, as is,
then put them in a jar of water with a drop of detergent and stick
that in my ultrasonic cleaner. This usually gets all the grit out of
those tiny areas and recesses on the trucks; I then use the tool
sold
by ReBoxx to ream out the axle bearing holes. I think grit blasting
the plastic trucks gives a great weathered look for our steam era
freight cars.

YMMV

Is there a reason to 1)sandblast a styrene kit before painting or
2) prime a styrene kit if it is already grey ???? such as an
intermountain kit
