- Clean with acid solution and water
- Apply WG 6650 Wash primer, one thin layer (10-15 micrometer dry)
- Apply P 05 Strontium Chromate Epoxy primer
- Top cote(s)
On the inside P 05 Strontium Chromate Epoxy is enough (no need for the wash primer). Air France and Eurocopter use this method and these products. The wash primer is used for other applications also (cars, trucks, boats), but with different epoxy primers on top depending on the application.
But, my RV is not going to fly several hours a day, seven days a week, year after year, and it is not going to fly shuttle traffic to oil installations in the North Sea year after year. On the other hand, my airport extends out into the sea, and according to technicians working there, it is a very corrosive environment. Tomorrow I am going to hear about price and availability of P 05, will se how it goes.
Still waiting for the new parts, it has been very quite from Van's.
Set up the primer booth more properly with a separate compressed air line with pressure regulator and water removal, purchased at Biltema. Built a primer table (235X53X75), only lack the chicken net. If the P 05 Strontium Chromate Epoxy is going to be used I will also need some more substantial ventilation than door/window, at least a fan.
The WG 6650 wash primer contains Zinc Oxide and some phosphates of some kind.
