REFLECTOR: Zinc Chromate vs. Zinc Oxide

[Craig and/or Denise Woolston]

I'll second that on both comments, great stuff, but nasty smell, and
overspray.  Isn't it true that most "good stuff" is also bad for you.

If it doesn't work, then google mar-hyde.  It is a single step self etch
primer made by Bondo corp.  It comes in an aerosol can which is a good deal
over having to mix two part primers.  It puts out a thin coat so plan I
having to do several coats.  ...and it's nasty stuff...no two ways about
that part of it.  A good mast and good ventilation is a must.

I have some parts that I need to prime, and I know that zinc chromate has
been the primer of choice for years, but due to the chromate supposedly
being a carcinogen, is not as popular. AS&S lists zinc oxide right alongside
zinc chromate and says that they're fine for aluminum and steel. (I have
some steel I want to prime.) My local paint store can't get zinc chromate,
so I asked them to order a can of zinc oxide. I checked out the label this
morning and it says that it's for aluminum, magnesium, and other non-ferrous
materials. When I read that, I interpreted it as meaning "no-steel"; steel
is ferrous, isn't it?

 

So should I order a can of zinc chromate from AS&S, or go back and get the
can of zinc oxide? Thanks for your help!
