Bulkhead longevity

Hi all I replaced my door hinges today and thaught that it may have been a good time to pop something in the bulkhead like grease/oil etc to preserve it!? it’s currently mint, and I’d like to keep it that way!
Any hints/tips? Cheers!

Get a Dinitrol kit with a pipe to get in to cavities. Have a browse on here https://www.dinitroldirect.com/?utm...p7nHgcQZapR5S2iER8mt8edI7cAC5p_QaAgj6EALw_wcB
and then buy the appropriate dinitrol from wherever.

Having just done this with mine (part the vehicle as part of the rebuild: link) one thing I will say is it is not as easy as just getting the kit online. I had several problems documented on this thread: link. My compressor was not powerful enough (cheap diy job) so had to shorten the pipe on my spray gun. I also had to heat the wax to get it to spray at all. Whereas it is easy to do and I would also say use dinitol it is not as straight forward as I was lead to believe, not the application or the product but the correct equipment/tools required to make it easy.

@Cadno , as per above, the Dinitrol kit/s are very good and easy to use. I did mine last year getting into every bulkhead nook and cranny including a thorough treatment into the full length of the A pillars - these are easy to do when changing the door hinges. Hint, 1. in this colder weather place the cans in a bucket of hot water before use, and 2. it's worth shopping around for the bulk can supplies as prices can [see what I did there? ] vary.

Also, Dinitrol 4941 is excellent as a surface protector in/all around the rear cross member - I use this as a final spray/wipe over after cleaning, same to front bumper [inside and out], tree/rock sliders [inside and out] [I drilled 5mm holes for internal application] + any other parts that need protective coating.

Squirting stuff through the hinge bolt holes only gets it to some bits. Remove lower bolt of screen bracket in cab for more access. Been doing this for years on mine and still have only had to do some very minor welds on it . 1990 Ninety.
