Before drying it can't be colored without disrupting its functioning. After complete drying, which occurs in 30 days, it can probably be colored safely. I haven't tried it so I don't know for sure.
You cannot brush it on. You will need to use a trail.
If the tarp is over a structure like wood, yes the sealant cement will stop the leaks.
It can probably be applied in all Earth ranges,. It has something like gasoline in it so it's probably going to freeze in the winter, it'll probably cure normally.
I actually get really good results at getting off my hands and tools with plain old shortening.
The rain may not damage it, but the volitiles will run off and probably stain everything they touch because they take a while to evaporate.
Its first initial drying occurs in 12 hours. It's mostly dry but still moldable at that point. After 30 days it dries completely and turns solid.
Yes, but only as a short-term stop-gap fix. Long-term, unless your shingles are black, it's going to look terrible (messy). Also, if the shingles move, even slightly, the roof cement coating will crack and will need to be reapplied.
