hmm i got all this used black thick engine oil in my shed that i was looking to dispose of in the spring....BUT...what about possibly using it for some undercoating and coating certain hard to get places? (use a big paint brush)...maybe its atotal no-no and u guys will laugh...it just kinda popped in my head

 

Why not get a cheap filter set up and "dispose" of it in your fuel tank?

 

huh? oh ur being serious

 

Well, I have heard of quite a few people running waste oil, you are officially the first to mention undercoating with it!

?

 

Waste oil is full of chemicals and acids from the combution process and not a good idea to use as rustproofing.
Besides new engine oil is cheap.
I have heard that transmission fluid is much easier on rubber parts...but then again you can probably find "oils" that are rustproof specific.
Such as "Rust Check" or "Krown"

 

oh yeah i know i can get that done...heck for 95$ i can get the truck rust proofed...it was just thought...the whole rust proof oil is basically petroleum based in amuch thicker form...its just a much thicker WD40... ..

 

Or you could install a waste oil heater and have free heat for the garage/workshop. I have installed quite a few of those in the past couple months.....the oil change shops seem to be using their noodles now!

 

.....my granfather used it on a 79 ford since the 80s and it never rusted bad underneath.

 

really??? thats what i like to hear...and ur out in the crappy snow like me...there's more salt here by my way then there is grass!

 

Well its messy..but it is pretty effective...he actuallt uses it one the truck he drives now. We use an air powered sprayer to aply it.

 

Works great on wood trailer decks! WAAAAYYY better than thompsons on something that gets heavy traffic.

 

Are you talking about using a brush to apply the used oil. My 8x12 sled/atv wooden deck trailer has one year old decking on it and needs to be re-coated. I was just going to get some waterproofing stain, but now???
Does the oil soak in well? I don't want oily boot bottoms after walking on the deck.
btw, where did you get the brush gaurd on the white sport in your gallery???
