## Customer Reviews

### ⭐⭐⭐⭐⭐ Looks ok to me
*by M***P on 17 May 2025*

Arrived on time- haven't used it yet.

### ⭐⭐⭐⭐⭐ Good and proper!
*by A***E on 26 January 2025*

This is the stuff you want if you need a water tight seal on pretty much any surface.We had some conversions done on out new fleet of vans which left exposed wood on the bottom of the Luton bodies. Not ideal given the weather.Brought a can of this stuff to spray seal the exposed wood and it worked like a charm. One can did several vehicles. Goes on very easily, only a couple of light coats is more than enough. Touch dry in perhaps 20 mins and fully cured in less than 24h.Once its fully dried is hard rubber and fully water tight.Would highly recommend this for the price and also consider the paint on version if spraying isn't an option.

### ⭐⭐⭐⭐ nothing
