• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web.

After weeks and countless hours of reading these boards I feel that I have a better understanding of what I am trying to accomplish. I've heard of people doing an MEK test on parts that they've had powder coated. Initially I did not understand the reason for the MEK test but now I understand.

Here is my question:
My project just acquired was sitting for many years. The green coating on the frame (zinc chromate I think) has some areas of light rust. My project won't see any covering for about a year. I want to spray (rattle can) a 2K epoxy primer to preserve and prevent any more rust from forming.

This morning I called the shop that plans to cover (subject to change) and he said so long as it is a 2K I won't have any problems, no top coat needed. So my question is, should I still do an MEK test? I haven't decided if I should use the Rustoleum or the Eastwood 2K product. If anyone has a suggestion please let me know.
