Protecting bare metal in humid weather?, Weather is not cooperating:( Options

[Jon H.]

I took my fenders down to bare bare metal a few weeks ago and welded on some flares and I finally got the welds ground down. It has been raining here in Ottawa 5 out of 7 days since the spiring and the humidity is horrendous. Things are starting to look orange (IMG:style_emoticons/default/sad.gif) I have no HVAC system in my shop so it's difficult to control the environs. I do have a wood stove though?

1) will epoxying the metal in high humidity be an issue?
2) will using my DA sander on the orange be enough or should I use metal prep too? Last time I used that the whole panels turned orange right away? And then to wash the panels with a hose didn't seem right (IMG:style_emoticons/default/confused24.gif)
3) is there something else I could do to preserve the metal until the weather conditions improve that isn't to much work to take off at a later date?

Thanks

Jon
