[Hallicrafters] BLACK WRINKLE PAINT

[Charlie]

KRYLON (Sherwin-Williams) also makes a very good black wrinkle paint.  Their
stock number is:  #3370, "Jet Black,  Wrinkle Finish".  I was able to buy a
case of it very reasonably from a local Sherwin-Williams outlet a while back
for about $4 per can.

I have found that to get a nice light wrinkle, follow the two coat procedure
printed on the can and bake it in the oven at 150 'F for a couple hours.  I
have never been able to get a uniform wrinke from just air drying.  It takes
the extra oven heat to do it right,  plus that will harden the finish better
anyway.  Do one horizontal surface at a  time, which is a pain because it
take so long, but a "run" will scrap the whole project!  Using three coats
results in the wrinklle being way too heavy, sorta like those old Bud
chassis where the paint was so thick it flaked off.

I have to admit though, since we've been recently doing the powder coat
wrinkle, I have painted very few items with the Krylon stuff.
