### ⭐⭐⭐⭐ Review
*by T***R on 10 August 2024*

I bought the gallon size. It arrived packaged very well, secured top and bottom with Styrofoam in its own box which was placed in a larger box. The lid was secured with 4 clips to keep the lid on, though I was able to remove those clips with my fingers. It is quite thick. Not like putty but more like a very thick molasses. It will pour but you'll need to spread it out. It will self-level somewhat, but I did apply this on a flat surface in sunny 80-degree weather, and that probably helped it to self-level. On a cooler or overcast day, it might not. It seemed to cure in just a few hours. There are a lot of fumes that comes off this, so excellent ventilation is needed. A smooth substrate will need to be sanded to allow it to stick well to a smooth surface. I had no problem. Directions say that it cannot be painted or accept other coverings, but from a YouTube video, Flex Paste will adhere very well to it and Flex Paste can take other coverings like paint and such. The can re-seals well, and I'm confident that it can be stored for a long time in a closed can and still be usable. This is a good product that can seal many problem areas.
