Thanks Watermann. I also re-read Woodonglass tractor paint tips. Again, I am amazed at how much I missed or didn't retain when I was reading his instructions prior to starting.
The quick dry zinc chromate didn't have thinning instructions and it was thick stuff...
I called the manufacturer's tech support for thinning advice, but their guy was out that day. I decided to use it straight out of the can and lay as thin as possible.
Seemed to go down okay (I am saving these pics on my harddrive as landscape rotated but they are reverting to the original when I post

)
Next came the two coats of primer
then the first top coat (with hardener and acetone)...
It was too late for a second coat. I will add that today, but we had a 25 degree temp drop overnight. Low 60's all day.
How long should the 2nd coat dry before putting back into the water? Is 24 hours sufficient?
