It also needs to be safe to carry the spray kit in the back of the plane, for de-frosting it away from base.
I know the stuff which does that (I use it in the prop TKS system) but it cost me £200 for a 20 litre drum
It depends where, but Kilfrost RDF is pretty good, if not cheap. Aeroshell 07 works well too. You don't have to heat it which is a benefit and it's fine undiluted through a sprayer.
It is safe on paintwork and aluminium and unlike generic car type defrost stuff, it's safe on perspex windows too. Though I have seen lorry deicer that seems to be the same as Aeroshell and a fraction of the price, but I haven't used it myself.
I've heard of some de-ice pellets from Kilfrost that you apply by hand too, though I've not used them. Has anyone any experience of them?
If you're paying £200 for a 20 litre drum of TKS fluid, then you're getting done!
