I am in the process of restoring the rear end of my 70 coupe. I have everything torn out (TA's, Diff, Gas Tank ect..) and have cleaned most everything with a wire wheel. My question is how warm does it need to be to use the POR paint? Middle of winter here in Cleveland and my car is kept in unheated garage. When I work I fire up a Kerosene tube heater to get the chill out but it rarely gets above 50 degrees and the parts I want to paint are all cold soaked. Has anyone used POR 15 at around 45-50 degrees? I really dont want to wait til spring to paint....

Also, has anyone used the gray and clear POR 15? Does the gray come close to the cast blast color. Should I just use the gray POR or paint the diff and half shafts with cast blast color and then top coat with clear POR 15? Anyone use the clear or gray on a new gas tank??

From the POR15 website:

"WHAT TEMPERATURE AND HUMIDITY CAN I APPLY POR-15 IN ?
POR-15 should be applied in temperatures of 50-90F degrees (10-38C) and humidity under 80%"

Think I was in the 50s when I sprayed my frame... I just insulated my garage doors and was able to get my 3-car garage into the 70s in a couple of hours with a kerosene heater... Like you mentioned, just because the air temp is in the 70s, need to ensure the metal parts you are painting are warm as well... Heard folks wrapping or draping electric blankets over their parts...

If the parts are small and mobile, place them in the house over-night and them try to get the garage as warm as possible before moving the parts out to the garage...

If you heat up a cold garage, your humidity will be high, and the cold metal may sweat. Paint the parts in your house when your wife is shopping!!!
