Im probably wrong but I though the 90/110 models used foam seals and the earlier series used rubber ones?
Defender ones fit to the flap and series ones to the bulkhead?
By mistake I bought the series ones too. Was your paint ok with the bostic Flossie? I decided to get the right ones. Got the rubber ones in reserve I suppose. Self adhesive ones take 10 seconds each to fit.
Yes paint is fine. I fitted the foam ones first and they were rubbish but it was too long ago to remember why! Must have been leaks of air and or water probably. Maybe they were in a blue bag and genuine are fine? Dunno...
But no issues with the rubber ones cept slight air ingress 8 yrs on.
The rubber ones seemed too thick, to me, for my my vent flaps. My new ones haven't been tested as the Landy hasn't moved yet since I fitted them. Good to know the bostic didn't affect your paint.
Self adhesive neoprene section from ebay has worked well on the series stuck to the bulkhead and the 90 stuck to the vent flap, easy to fit and seem to seal well.
The rubber ones on the series were a nightmare and in the winter my bloody hands froze!
