Interesting.......
WLS is a two part epoxy primer that provides good fill qualities.
Today there are much better alternatives (two part, water based) that
should be investigated for they only require that you roll it on - as many coats
as needed to fill - and then just sand it once to a final finish before painting
(or flying).
I used three coats of WLS back in '94-'95 and was pleased. Each coat
required one week of prep (paper on the floor, plastic covering everything else,
surface cleaning), 20 minutes to spray and two weeks of wet sanding before the
next coat.
I mask sprayed Krylon N-numbers on the side and after certification flew
the plane in primer for a year before it was painted.
One problem that the primer surface had was that it was extremely
conducive to the formation of static - so much so that running my hand over the
cowl would cause the hair to stand up on my arm (Loran would never work once
airborne, forcing me to switch to GPS before its time).
After removal of the Krylon and a final light sanding, the plane was
painted (PPG automotive base/clear) - lo and behold, the Krylon number area was
swollen and, in the right light, one could make out the old numbers. It
took about 6 months for the swelling to disappear. Today, in fluorescent
light, I can see the weave in the e-glass cloth underlying the paint and
primer (disappears in sunlight).
If I was prepping today, I would never use WLS. Times have
changed.

with it. It sprays good , sands good, and has good hold out qualities.
The worst thing is that it takes overnight to dry.
In case you are not familiar with paint, hold out
means that it will nat allow other paints to penetrate through it and swell
sand scratches, pits, cloth weave or whatever.
Its good stuff.

Spraying?
LML Members,
Does anyone have any experience in spraying WLS Coatings epoxy
primer?
The kit consists of 1 gallon
of (The Aerocraftparts website says Primer, but I think it is the Resin?)
with 1 quart of Catalyst and 1 gallon of Reducer.
I gather you use the Reducer
to thin and clean?
Thanks
