Review: Worth the Money, no problems, good stuff! - I couple of different A/C business owners, I know, suggested this for small leaks on the house system. I just recently bought some more, since I needed to add freon to my system. The original same product has been in my system for 12+ years. I've never had any problems due to this product being in my A/C system. The A/C owner/personal friend of mine suggested using a paint gun to push the plunger in on this product and it certainly did make it a lot easier to get it in the system. Also I would recommend installing this product while the system is low on freon, before topping off the system. It should make it easier to get the product in the system.
Review: Seal - Need to be careful when applying but works
