Well guys, the rust comes.

I have a 1994 Nissan p/u. 190,000 on the engine, thing runs awesome. But my frame is getting really bad as far as rust holes and key stress points. Is there any thing that I can do to stop the rusting, and repair it? I love my truck, and I will do anything to keep it from breaking in to two piece's while driving down the road. lol

the hb truck was introduced as a tough little truck .
but after 90 they made the truck lighter and started using the ka engine.

so after 90 the frame rust out a lot faster than the previous.imo.

so find a pre 90's truck and bring over your engine and trans or sell your parts and buy yourself a 86.5 to 89 nissan truck .
if you like the z motor keep it if not put your ka in..

btw my z24 engine has over 500 k miles and it it is an 87 hb..

sort of pulling cab and bed of and sand blasting and welding in plates to re inforce the fram then useing something like por 15 to paint it you can get under there sand and repaint
