I have now a df150
I spray wurth HHS 2000 its waterproof crease and does not dry out
I spry this under the cowl about every 6 months I just spry it on I don't de grease the engine
it keeps it like new
been using this for years
my last engine I sold I had for 10 years under the cowl it was like it just came from the showroom
I also use it on my trailer rollers and break cables and under the engine ie the hydraulic rams and the trim and tilts
every where this is good stuff
