[Milsurplus] Milsurplus--- wrinkle paint

[AI4WM Bill]

To all those who bake and otherwise heat their wrinkle paint.  Thanks.


I just tried 2 old enclosures I wanted to paint.  Since I never heated my paint I gave it a try.


One in my transite oven and one with the heat gun.  

Both methods worked fine.

The heat gun was faster, but not as nice even texture of wrinkles as the oven.

The oven took longer, but the quality of the finish was much more consistent and nicer.



I always say there is something new to learn... I learned something.


73,

Bill

Greetings all...  I've never had any trouble with  VHT black wrinkle--we get
from 'petrol head' shops.
Baking does 2 things...........
1. makes it wrinkle evenly and ...
2. hardens it up and NEVER sticky. I bake for 1 hour at 212F /100C
Clean panels-- yes...  remove ALL  previous finishes .... thin coat for fine
wrinkle.. thick coat gives coarser wrinkle.
Kitchen oven takes BC-348 case--- smell goes just before the  XYL gets
home.!
I've done about 20 X BC-348 over the years, ARR-15 and ARC-2 front panels.
Some use a big box with a high wattage lamp to get and keep the temp .up.
Waving a hot air gun at it is  doomed to  give  spotty results.... even temp
the clue.
A dossier on this wrinkling  process should be in the archives..... I've
made dissertation on this topic a few times.
Similar labor of love applies to R-390 knobs  e.g except gloss or satin VHT
used but baked... the high temp stuff they sell for use on auto exhaust
works fine. 
Pix of recent efforts on request.
