Asked by rav January 22, 2021It is not recommended to thin 208. 208 Is made to a specific thickness in order to stop leaks. As an alternative for small cracks and the convenience you could use the black TropiCool 880 Stop Leak Spray silicone. This product allows you to spray the Stop Leak into hard to get to spaces or any small cracks. Thank you for putting your trust in Henry products and the Home Depot.

Asked by AB June 12, 2020It’s 90% of a gallon. It’s like the reduced size packaging at the grocery store, you’re not supposed to notice it’s not a gallon. If you actually need a larger quantity find the 5 gallon cans.
