[ARC5] Wrinkle paint

[Michael A. Bittner]

I agree with everything Ken said except I just let the item sit, painted side up, in the California sun for about 4 hours. The black color results in the item getting uniformly hot enough to start the wrinkles and then dry the paint.  When all sides are done, resist the temptation to do further work on the item for a few days in order to let all the paint thoroughly cure indoors.  I use black wrinkle paint from an automotive parts store and I've also used this method with olive drab wrinkle paint from a fellow who was selling spray cans of the stuff at one of the MRCG meets.  Anyone know who that was as I'd like to order some more?   Mike, W6MAB

  I have had excellent luck with the automotive exhaust-system paint 
  that Robert Eleazar mentioned.

  However, I always paint whatever I am painting with that part lying 
  flat. I don't attempt to paint vertical or angled parts.

  Secondly, I "force" the wrinkling with a hair-dryer or paint-stripper 
  set on low.

  The wrinkling looks very good, although the wrinkles are a bit fine. 
  The original wrinkles are about twice as "coarse" as what results 
  with the use of the above paint.

  The thicker one can apply the first coat, the more coarse the 
  wrinkles. But if you apply it too thick, you get blobs. It takes some 
  practice to get it just right.

  Thirdly, I always completely strip the part I want to paint, and if 
  it is aluminum, I wash it with white vinegar, then rinse with water 
  before I start.

  IMHO, a finer wrinkle is better than no wrinkle at all. :-)
