Was there any primer used, or the HS35 is a topcoat that was applied direct
ly to the etched metal? I'm just trying to understand the whole picture. No
rmally a gloss topcoat requires a flat primer over any substrate to bond pr
operly.

Looks like Valspar- HS35- two pack acrylic paint doesn't stick at all o
n to Prekote treated 6061-T6.Just did the wings and the bloody paint peeled
off in sheets.All the other bits I alodined and no problems with the Vaspa
r HS35- paint.It appears that some of the two packs don't like water base
d etching agents so prior to painting your aircraft do a sample piece first
to see how well it- adheres.Cheers

The Valspar HS35 two pack acrylic paint is the primer and if the topcoat [two
part as well]is applied after 1/2hr and before 2hrs it does not require sanding
as the primer is still tacky [chemically]. This method is great for surfaces
with protruding rivet heads.The only conclusion I have come up with, is the temp
was only 20 deg C and there may have been moisture in the air line????? Cheers
