The underside of my car is in pretty good shape and i'm looking to keep it that way, and therefore was thinking of taking it to a local rustproofing/undersealing specialist who utilises Dinitrol. Was also keen to get them to take off the old underseal and touch up any existing rust grumbles prior to a full coating, and installation of wheel arch liners.
Therefore i was looking to dip into this forum's seemingly endless pool of knowledge and see if i'm just about to spend my money in the wrong place!
Thank you!

Dinitrol as a product is one of the better ones that I have tried.
The thing about all of these preventative treatments is that they really need to be used on clean rust free steel. If you just smear what ever gunk you choose onto rust all you are really doing is making a bigger nightmare for the welder who will have to come along and fix it proper (!)
Removing old underseal on the underside of a car is one of my least liked jobs. I expect to get someone to do the job for you and for them to do a good job it will be a very expensive process. I imagine many commercial solutions would rather involve acid baths just because it is easier for the man power.
Having owned 1980's and 1990's Mercedes with their rubberised undercoatings I know that the rubberised solutions are not great in the long run. As soon as water gets under the skin of rubber it gets sucked along resulting in much larger rust problems than there would have been if there had been paint or old engine oil...
...my PV544 is in a much better state than many modern vehicles and has lasted longer than them partly because of slightly thicker steel but mainly because of the old tar based underseal treatment it had (that didn't spread water like that rubberised ****)
