Today i was at Wings on gold coast with Harry Mason who is our local Diamond service centre. He has used the PPG product per diamond instructions. He showed me factory cowls and ones which they refinished here in AUS. He also showed me little glass plates on sides of aircraft fire walls which also had to be done. It is then covered with clear 2K which protects the fire proof paint and seals it preventing it drying out. It also makes cleaning cowls easy. . 5 lits is $620 from Melbourne. The cowls are smooth and easy to clean. He brushed it as less wastage as it is so expensive. Roller would look better maybe.
I do notice the later h36 have fire proof paint aft of the firewall by 60cm on underside. This has been a requirement of CS22 since late 80s I think as I do know Scheibe added a removable aluminium sheet in this area before 1990 to meet this new requirement. I also went to mach1 to have a 250hr service on slick magneto and in November 2018 there was an AD to replace the large cog in slick 4330 magneto and has to be done within 50hours of Nov 2018. Gather the method of manufacturing has changed and parts are readily available now finally. Diamond also issued the slick AD but must have forgotten they also have h36 with slick. I should have the AD tomorrow electronically for slick.
