You noticed any problems with lead mastic. I'm seeing alot on sites these days cracking. Looks like it's shrinking and there like it's leaked oil out of the mastic can see brown oily stains on it. Just convinced a local roofing merchant's to switch, the problematic mastic are either premium or bond it possibly both.

@@P4ULM4C I’ve not had any issues with it mate
We only use CT-1 never any shrinkage or cracking. Bit more expensive than other sealants but you get what you pay for.
