I got a lot of steel panels, and constructed a large (32' x 40') structure
out of two 40' containers. I used a lot of painted Fabral MightyRib panels,
but had to use some galvanized ones, because I got a killer deal on them.
Now it is time to paint the whole thing. For the galvanized, what is the
best way to prep the surfaces so the paint will stick? We get blazing hot
temperatures in the summer, upwards of 150 degrees surface temperature, 110
plus air temps, and 130 plus inside the containers. Winters bring weather
in the 20-40 degree night time temps.
A friend of mine a long time ago, who was a professional painter, used some
common vinegar to paint some for me similar to these. It was for a
commercial job, and I never did go back and look at how it aged. I never
got a call from the company that there was anything wrong with them, so just
plain don't know if they did good or not.
Besides vinegar, is there any other treatments? Estimated 150 square feet,
uneven vertical surface.
