Dynatron 550 Auto Seam Sealer Grey Caulk - 12 oz.

Q: What is the recommended ambient temperature range for applying this seam sealer?

I use it between 50 and 90. Near 90 it almost skins too fast. I smooth it out with mineral spirits on a finger.

Q: Can I fill a vertical seam without it running? Is it thick enough to stay in place on a vertical panel?

Absolutely, vertical application can be applied. I did it.
