Epoxy Primer Tempature

M

I understand that the surface tempature of the car has to be 70 degrees and above for atleast 24 hrs after spraying the car. I do not plan on painting the car for months after i put the epoxy primer on. The primers purpose right now would be just to protect it from rusting. So i would have months for the epoxy to cure properly i would think. I know i will have to scuff up the surface then apply another coat of epoxy to begin the paint process. Ive been waiting for the weather to cooperate and it always seems that on the weekends when im off the tempatures are not ideal. Today temps are gonna reach 80 and a low of 63 at night. My question is would it be alright to use the epoxy primer knowing it will have a few months to cure properly and i wont be doing any body work or painting soon? Also tempatures are just going to get warmer. I live in Texas by the coast.
 
Way back when I first started using SPI epoxy the 2009 tech sheet said:
Cold Weather:
In cold shop conditions this primer can go dormant. Try to keep heat on car for four hours
after spraying with a minimum metal temperature of 60° F. Also, when cold it will help
to mix primer and let it induce 60 minutes before spraying. Application of any epoxy in
cold weather can destroy a paint job. If you have any questions regarding the
application of SPI Epoxy in cold weather please call us first. Metal temperature
when you spray is critical and must be at least 60 degrees!


I have been following that guideline and never had a problem. If you can keep the temperature in the shop above 60 degrees for at least 24 hours you should be fine in my opinion.
 
Im gonna give it a try. Gonna do the doors and see how it goes. That way if it doesnt take it will just be the doors and not the whole body. Anybody else have any suggestions or opinions?
 
Prefer not too with all the pollen and bugs out right now.
 
Plus neighbors always seem to want to cut grass when i have parts to paint.
 
I think he means after they have dried to the touch. A few hours in direct sunlight will help speed up curing immensely.

Second what Mitch said. If you put the parts out in the sunlight for 4-6 hours that would be ideal. Do that and you don't have to worry keeping it above 70 for 24 hours. UV light from the Sun really helps the Epoxy cure out.
