The trick I was advised of with wrinkle paint was to 'force it' with it a
hot-air gun. I have actually had good success using aerosol-can wrinkle paint
AFAIK, most wrinkle finish work involves baking.
Here's an old ARRL
"Hints and Kinks" item on the subject:
Yes, but the texture of the wrinkle varies greatly with the baking and
paint formulation. from an auto-supply store and an old hair blow-dryer.
Some patience required,
but you can actually control the depth of the wrinkle with
the hot air
application. The result is a vast difference from just leaving the wrinkle
paint to dry on it's own.
This was on an aluminum chassis with an aerosol-can flat lacquer first coat.
The aluminum was sanded (emery cloth and/or garnet) and washed with TSP and a
long hot rinse before painting. (Criticism welcome if some fault is to be
found in this process.)
