Undercoating

They all work, just comes down to how long it will remain before it's washed off. Here in New England its not going to last more than a year in many places on the chassis.
 
A 2009 study found that approximately 70% of the road salt being applied in the Minneapolis-St Paul metro area is retained in the local watershed.
It's the same place it goes here to, They load all these road, and parking lot snowbanks into large dump trucks that dump the salt, and snow onto the major river banks along the town. it doesn't take a genius where the salt ends up.
 
some undercoating long ago on that forward facing bolt to the washer jar tank housing sure woulda helped me out in the current fiasco of replacing grommet and pump or wherever its leaky from
 
Just go to the hardware store, and buy a qt can of acetone, and a qt can of marvel mystery oil.... mix them together, you'll have all you will ever need. If you can't find the marvel mystery oil, ATF works ok to.
 
so after a year of application the cosmoline sprayed upon the prop shafts has started to seriously wear off and looks fugly again.
? do another reapplication when the weather warms a bit for the product to spray?

or should we look into powdercoating the propshafts to make look badAssry underneath taco
 
That driveshaft looks so pitted it looks like if you whacked it with a hammer it'd break right through. I didn't coat the driveshaft on my tacoma fearing it could throw it out of balance. I didn't on my tundra either, and it was ok the nearly 20 years I owned it.

tundra driveshaft never went crusty rusty in all that time?
 
Not quite as bad as yours, but it had a fair amount of surface rust.

my relatives '11 with 75k miles is starting to show some crusty popup spots here & there

should i splurge on a new propshaft? that could be some of these weird illies got going on underneath IDK IDK IDK
LOL
 
Well, seeing what you already have into this truck, which is probably more than a newer used one, its your call, it couldn't hurt if you like new parts.

Newer used one like a '98?

Honestly I did not care much for the redesign done inside and out!
