Video: How to use spray primer on plastic parts
Is the primer acrylic- or oil-based?
Hope acrylic is used, oil base can damage the plastic & not as easy to clean up
hope the paint you used was acrylic
Is that primer good to use on N scale models, with small detail parts? I know that is an thicker primer
Another tip. You can also clean out the internal part of the spray nozzle the paper towel cant reach buy turning the paint can upside down and spraying until the paint stops coming out.
Chris is right. His tip is the best way to clean out the paint in the nozzle.
David Popp mentioned that the primer is fairly thick, which is true. I use Wal Mart’s own brand of primer, Color Place, which does not have any filler and is very thin. It is also very inexpensive, about $1.00 per can, and comes in white, gray, and red (primer red).
Clean the inside of the spray nozzle by inverting the can and spraying a blast of clear propellant.
If you didn’t follow cleaning instructions last time, removing the tip and soaking is solvent (e.g., lacquer thinner seems universal) overnight cleans them up nicely.
Is using Rust-Oleum Automobile Primer or Wal Mart’s Color Place Primer compatible with Polly Scale Railroad Acrylics? Are their any precautions to follow when using either of these primers with acrylic paints?
Very useful. Would Like to see more of this type of information.
How about using newspaper plastic bags for your mitt for holding the pieces?
Kitbashing requires new paint. Thanks for the tip. I’ll check w/my local automotive paid dealer. I was looking for a better idea, this looks very promising and quick.
to JOHN DULONG -
As an industrial designer, prototyping models are made of acrylic, polycarbonate and styrene… and all are quite compatible with AUTOMOTIVE paints.
I use touch-up paints in small cans from the auto supply store when BIG cans confine my color selection.
Also… sprayed from a greater distance will allow the paint spray to partially dry in the air before landing on the part… when done lightly with a contrasting color between the paint spray it makes a shortcut to a weathered look! I use Brown primer for a rusted appearance. In one step it’s perfect at a distance!
Will RUST- OLEUM harm the plastic model parts? I always used primer from testors paint. What about the plastic fusion paint from krylon paint? Will that work on styrene plastic?
David:
If you turn the can upside down and spray, you will clear the internal paint tube, then wipe off tip.
