[AT] Acrylic enamel paint hardner????

[Spencer Yost]

I think you are lumping all the types of enamel together and getting
confused that way.   When people say enamel, they are never talking about a
true alkyd enamel.   They are talking about acrylic modified alkyds or a
true acrylic enamel.  You can add hardener to any acrylic modified enamel.
Very few folks use true alkyd enamels anymore.  I understand virtually all
are acrylic modified, even if they don't say so.  My supplier is Piedmont
Light Industrial coatings and sells the hardener and paint together:

As you can see, this is sold as a set and works great.  It is an old
fashioned alkyd base but is acrylic modified - that is why I can't believe
your suppliers played dumb.   They should have at least said "You can use
it in acrylic enamels, but shouldn't in 100% alkyd enamels".   Adding
hardener to any enamel is common and adding hardener to acrylic modified
enamels is industry standard practice.

However, this doesn't answer the question - Should you use in 100% alkyd
enamels?    I'll let other jump in because I have always hated true alkyd
enamels as too slow drying and soft.   I have seen it done and turns out
nice but that doesn't mean it is standard, right, professional or anything
like that.
