    Well the "hole" in my gat tanks turned out to be "holes" and lots of them, so a new one is on the way and I have a few simple questions for y'all. First off what kind of paint/coating should I use on the new tank to protect from rust? and second where can I get a skid plate or a plan to build one or even just some good pictures?

    My 1990 came with a factory skidplate on the gas tank, so you might be able to find one at a boneyard, or maybe try a dealer. As far as coating the tank, find something good and rugged, that also ends up smooth (so it doesn't hold mud in as good) I've heard good things about POR-15. Let me know how it works out, the same thing is on my project list.

    Why do people keep calling it a Bronco!!!!! [​IMG]

    I never did find a good skid plate for my old 75 Blazer. That tank (seems like mine was 28 gal??) is in a terrible place! I eventually lost at least 5 gals (probably alot more) of capacity by caving it AND the skid plate in. There was a thin plate (factory?) on it when I bought it but it was quickly obvious that it was not sufficient. I got lucky and stumbled across a heavier one at a junk yard (looked home made but good) but even that didn't hold up. I always wanted to build a heavier plate but never got around to it.

    Anyways, my rambling point is that the tank is very exposed and needs some serious protection. I don’t think the factory plate is even close to strong enough for rock crawling. My K30 is getting a relocated tank above the rails (on the inside) and I’ll have to spend some time figuring out how to build plates for the rest of the exposed underside. A single heavy, bolt in plate from the engine oil pan going back past the 205 is my ideal but it will be hard to make I think.

    Hey, anyone got good pictures of good, heavy skid plates for gas tanks and/or other areas?

    I've got an idea for a gas tank skidplate - Fab out of 3/16" plate and weld 1"W by 1/2"D channel iron braces on the tank side. It wouldn't take too much to do, and would theoretically take all the abuse you could throw at it.

    i'd go with the por 15 i've used it my truck just make sure you follow the directions and it should turn out really good, i had a rusted battery tray that i used it on about 7 months ago it worked out well for me.

    I got a fairly beefy factory skid plate from a 70-something Suburban on my '75. It bolts to the frame in about 6 places and completely encloses the tank. It has drain holes so that mud doesn't build up between the plate the the tank. It's held up well, but I try not to slam dunk it onto boulders. [​IMG]
