How soon till the epoxy is hard

I am restoring a 66 mustang and have finished all my sheet metal work, stripped most of the car to bare metal and am getting ready to epoxy this coming week. I have purchase black SPI epoxy.

I am going to spray the underside of my car the best that I can. It is on wheels, so will will not be great, but I want to put a good coating of epoxy on the rails, welds and exposed metal. I know it is going to be tough spraying that close to the ground on my back, but I think brushing it on will look bad. After I am done with the underside I was going to wait, not sure how many days, till I jack the car up remove the front suspension so I can spray the outside of the engine compartment, followed by the engine compartment. So my question is, I am going to put the car on jack stands. The jack stand will be on fresh epoxy and will probably sit there for a month while I work on the suspension. I am worried about the jack stand embedding in the epoxy if I do it too soon, so how many days should I wait.

I will also be spraying epoxy on the inside and outside of the trunk and hood. How many days should I wait till I fill the parts over to epoxy the other side. I will also be storing these piece for an extended period of time. At my speed it could take a year to get them back on the car. Is there a proper way to store the pieces?

I have painted some items in the past and depending on what was put onto it (weight wise) or how it was stored the paint has 'moved' or be distorted. Many years ago, I put a magnet CB antenna on a paint job I finished 3 months prior and it sank into the paint. I do not want to repeat that!

Thanks in advance,
Chris
 
Depending on temp, i would let it sit a week before i put it on jack stands. This would also depend on how heavy you apply it. I would put it on stands before spraying the chassis, to get it higher. Then you could spot in the small areas later.
 
Like Phil, I can only guess!
Like he said, depends on so many things and under normal circumstances full cure may be 30-90 days.
I would fold some rags up and place between the stands and frame and be real careful.
 
You can always brush the underside with epoxy. That way you are sure to get most of it covered.
 
Man do yourself a favor, go to Lowes and grab one of the small Kobalt guns with the side mounted swivel cup. I have had one for a couple of years now and it works great.
I am far from an expert, but I can lay reduced Epoxy about as slick with it as anything else I have used, and the swivel cup really frees you up in odd angles and tight places.
I set the wall at 65 PSI and start with the fluid 2.5 turns out and fine tune from there...
I think you'll love it for the money.
 
Xjunkie,
Is this the one you are referring to?
