Pretty good
Did quite a good job on a shed roof. I used it outside and inside on the joints. Some leakage later, but only in one place, so I'll just use silicone sealant to fix it.

Aerosol roof sealant
It did what it was supposed to do. Easy to use, seals well, no mess and dries quickly. I found that two light coats sealed better than one thick coat.

Doesn’t work very well

Brilliant
It worked, nothing else did, and I was despairing at not being able to stop rain water coming into my static van. I sprayed this on the area when it was bone dry, and, what can I say? No more water ingress.

Sprays too thin. It’s more like black paint.
