Great "Theory" and one I am "trusting" but we'll see
Let me 100% clear and up-front, I just had the Service done so "promises made" are yet to be seen if true or not over time HOWEVER having said that the "concept" is certainly "sound." One can "soak" a myriad of things in "solutions" that then help rejuvenate them by replenishing "oils" (whatever) to return elasticity and/or a sense of (closer to) original "flexibility" of things (say, even Leather, any number of Leather treatments to try keep them from becoming brittle, dried out, cracking). SO, this makes a lot of sense and indeed I HAVE PURCHASED THEIR PROCESS/SERVICE but as they were leaving I was told "should be dry in about an hour" and frankly it better not be - the whole point was that the "treatment" be able to "absorb" into the Tar Shingles and help "restore" a bit of their original state and flexibility (not be dried out and brittle, the Leather treatment concept). One could apply any number of Sealants to try keep water repelled (that would dry and create an extra "barrier") but that is NOT what this is supposed to be - again, sound principle, and IMO "worth the price" to "take the chance" at being able to put off the whole roof replaced expense absolutely NOT in my Budget right now (try "buy me some time" to put off and let me prepare in the next 5 years to be better able to swing the whole roof replacement that is the only 100% real assurance at keeping your Home dry inside (in so far as, guarding against the Weather up there)).
