How much longer do I have to wait for Zaino to dry?? I put on a coat of Z-1 followed by Z-5. Has been 3 hours and still doesn't really seem to be dry I used less than an ounce of each, so I didn't overapply. My truck is in a heated shop (68-70 degrees) and outside it is about 29 degrees with 75% humididty, it is probably a little less humid in the shop but not a lot?? Any ideas on how much longer I am going to have to wait??
