## Customer Reviews

### ⭐⭐⭐⭐⭐ Great for exterior security panels and speakers
*by R***N on 27 October 2020*

Does exactly what it says, seals electronics from the elements. We used this on exterior speakers and security panels and it has solved our corrosion issues we’ve been experiencing on them.

### ⭐⭐⭐⭐⭐ It's messy
*by S***N on 16 July 2021*

Price was high but works

### ⭐ It is a semi solid gel.
*by I***E on 9 February 2022*

It works exactly as advertised. I was looking for something that works like a traditional potting compound, which would flow into a chamber and expel all the air to give a final solid structure. However, the product comes as a gel, that is semi solid. It does not flow into spaces in an enclosure.
