Hey, all. I had some problems laying down epoxy as a sealer last night. I did my usual process of blocking out to 400, blowing off with dry air, wipe down with W/B 700 and let sit for at least 30-minutes while letting my mixed epoxy induce for at least 30 minutes as well. After laying down the sealer I had a lot of areas which look like contamination. See attached pics. After banging my head against the wall I checked the date on the 700 and it was from 2017. It's been stored in 70-degree shop with very low humidity so I thought it would be fine. Is there an expiration date for 700? Thanks!
Troy.
