My Fluid Film Fail

The title says it all. First off I love Fluid Film and have used it for about 8 years (7 on my Old Tacoma). Last year I applied in all the usual areas as I did on my Tacoma. One of the areas was always on the inside bottom of the door where the outside body skin is folded and welded at a seam on the inside bottom edge. Well, on my Tundra it softened the bottom door seal to the point where it actually hangs out at the bottom of the doors. (I should have known better!) Needless to say I didn’t treat this area this year, but now I need to replace all four door seals. I should’ve known better.
Can anyone help me with the part numbers for these seals? I’ve been trying to figure it out but Toyota’s door parts diagram is confusing me.

 

Dont feel bad

if that’s your only oopsie then you’re doing just fine

 

Oh believe me, I’ve had plenty of oopsies !

 

Well I couldn’t figure out the lower door seal part numbers with certainty. I ordered them from my local dealer… $190.00 for all four!

 

I am about to spray my truck and thinking to skip oil coating on doors and just do a silicone based product .

 

Thats probably a good plan. After replacing my door seals I kept one of the old ones to experiment different oil undercoatings on.

 

I honestly wouldn’t worry too much about the doors rusting. Toyota doors tend to hold up well as long as some washing happens over its lifetime.

 

I use to undercoat cars for extra money. rubber parts are tricky some cars have zero effect from rust proofing vs others do.
When I talked to some of the brands about this problem they told me its best to silicone spray rubbers first before rust proofing that way the oil does not penetrate into rubber. the oil that does get onto the rubber will most likey wash off pretty soon due to silicone.

My new tundra I will be prepping soon for rustproofing plan of attack will be to silicone spray all bushings etc under truck first then I might go one more step and use some tape to protect rubbers some more. then I will start to spray.

I will not be doing hood, tail gate or doors.

I did notice on the newer tundras they are filled from factory with a wax based product. so they are protected.

its good practice to wash truck often.
