Ditto on the bed liner for an under coat. IMHO it works ten times better and last's a LOT longer.

 

Kinda late for that now... but didn't these things come with undercoating from the factory anyway?

 

My 75 didn't have factory undercoating... it now has bedliner under it.

 

Seems like that would be a lot of work. I don't have the shop for it either. I would have to take everything off the frame

 

this is good info because im gettin ready to pull the truck apart and give it some more protection plus i think it makes the truck look sharp,now what is the best diy bedcoat for the under belly?

 

It was a lot of work but nothing really in all I have done to our 75 and all that's still in store for it. I did the whole underside in a weekend, disconnected all the hoses and lines, wire wheeled/brushed almost everything and rolled/brushed it on. I did mine almost 5 years ago and it still looks good.

I used the Herculiner roll/brush on.

 

Is it REALLY even worth it? I mean if you keep. Your truck washed and clean then the salt and all that shouldn't be a problem. I think if this undercoat does wear off, I will probably just use paint

 

I guess it all comes down to a guys commitment to his truck. For me my dad bought mine new in 1975. At the age of 10 I helped him rebuild the engine, ok so I cleaned parts and chased tools, but it was helping. Then we spent the next 7 years driving up down the west coast hauling a camper and a travel trailer that was our temporary home from job to job wherever the Union sent him to work. After that the truck was retired and just hauled the occasional load of firewood etc until I got the truck in 1995. In 2000 I rebuilt the engine again due to a spun main, this time dad helped me.

I plan to pass this truck on to my youngest boy in 10 or 20 years when I am done with it. So yea to me the undercoating and all the other work I have done to preserve this piece of my heritage is really worth it.

 

Well I got the truck from my grandpa and I am planning on keeping it a long long time. But like I said, I got 95% of it... I think

 

I use the rubberized undercoat from lordco in the gallon cans and use the undercoating spray gun off the compressor. It is alot thicker than the crap in the aerosol cans and doesn't cost as much as the bedliner stuff. We have been using this stuff ( 3M, i think) for 15 years in the shop and also use it for a cheap alternative for bedliner too...
