As the title says, how long can i leave the sanded polyester primer before i spray my 2k on it? How long is too long because i read somewhere that it should be topcoated within a reasonable amount of time but that wasn't clear. The weather just dropped down past 55 degrees so i need to wait to 2k prime in my garage.

Thanks
Chris

Don't sweat it, as long as it's not exposed to heavy moisture for a really long period of time it will be just fine. Polyester primer is wetsanded all the time so some exposure to water is OK but if it's exposed for a long long time expect it to absorb. When the temps get back up just scuff it down with a red scotchbrite and apply the 2K, it'll be fine. Bob

Bob's right,Your good to go within a "reasonable" time frame.
Once the poly is on,it's sealed and unless you been spraying WD-40 or such,You should be good to go. You can always do a good wipe down with grease & wax remover to be on the safe side if you wondering.
