Since in IL there will be a few more months of temperatures below 75F, a primer that can cure at lower temperatures could probably make more sense in my case.  Searching aircraftspruce, I found the following one:  
It cures at temperatures down to 35F! 
Do you think this one may work well, too?  If you see any drawbacks in using it please let me know; I can just wait a few more months and then apply the more common awlgrip 545. 
Thank you,
