Opinions please.
If you have a Disco 1 that you want to keep and it has a solid chassis and has had all the usual rot points fixed (for the moment) do you think it is worth getting it professionally Dinitrol or Waxoyl treated?
Will this keep the rot away and hold it in its current position or is it too late?
Only saying because I'm looking at a 200Tdi that is (currently) solid.
IMHO, it is definitely worth waxoyling a solid disco. Whether it is best done professionally comes down to how much time you have to do the job, and what facilities you already have, or can beg borrow or ????
the more time, effort and skill goes into the process, the better, I.E. the longer lasting, the results. There is a well know guy who takes the best part of a day to treat an essentially new vehicle - I.E. one that is rust free - and he has rather good facilities set up to do this job, and little else. My point here is that to expect to make progress in rust treating a much older vehicle in a short space of time, is, IMHO unrealistic.
in my experience, its the inside bits of sections (that you can't see) that will bite you on the bum, Not to state the blindingly obvious, but the external surface of, for example, the chassis, is easy to treat and keep essentially rust free - but what is going on inside??? So, I try to spend more time gaining access to them, and cleaning them out etc, long before treatment - preparation is king. It takes time, can be as boring as hell, but I know of no other way.
I have no experience of Corroless, but do use fertan, (and Waxoyl), and have had good results them.
It obviously can be too late, but if the thing is solid now, then any treatment at all will extend its life...
