     I will check my temperatures next time. My shop is heated, but I
was venting cold air into it to help with the fumes. I was comfortable
in a long sleeve t-shirt though. It was 31F outside. The radiant floor
heat I installed in the shop is so comfortable. everything stays so
warm to the touch. I went ahead and painted everything with VariPrime.

I have had various shades of gold from just a dulling of the bright silver
left by the alumiprep to brown depending on how long I left the part exposed
to the alodine solution.  Also old solution does not turn the part gold as
fast as new solution.
