Question about spreading cancer under truck

[ToddJerad]

I want to go to work on some of the rust holes in my EB. I do have what some would say would the rust in usual spots (between fender and door panel, skid plates, and generally some on the inner tub).

I have heard some good things about Por 15 and even was told fiberglass could be laid down and por15 could be used as a laminate. I have some good size holes (some dime size to some i can put my fist through). I know cutting and welding is probably a better answer, but I have no plasma cutter and am not an experienced welder. Any one had luck or maybe other recommendations, was thinking of painting exhaust pipes and other areas of the underbody with it if it really does stop the rust? Is it worth it and/or other suggestions on application or use?

Lastly, any good tips on removing some old undercoating? Tried lacquer and paint thinner but just got knuckles bloody as **** going to town with a putty knife. Por 15 I guess has to bond to metal and the undercoating ontop of the rust will prevent bonding.

there is only one way to fix rust, and that is to cut it out and weld in new. If you put in new sheet metal then POR it you will have good metal for a long time. keep the fiberglass and bondo to a minimum. You can half a$$ a job many times or do it right once. As far as welding, the best way to gain expirence is to do it. Get yourself a wire feed welder and start expirementing, you'll be surprised at how easy it is. Finally to remove your undercoating and to find all the rust in your rig your best bet is to sandblast. Good luck!!

You can avoid welding, by using body panel epoxy to fasten new metal on. You can hold the new piece in place while the epoxy sets by using pop rivets. Definitely cut out the rust and replace with good metal. Get yourself a book on body work from a local book store like Borders, you will find it in the automotive book section. Body work is really not that hard and I, for one, find it very relaxing ans satisfying. It is a lot like wood working.

Good luck,

Thanks guys, I really like the rivet idea with aluminum sheets and will por 15 the body panels since it will be near beach. Ill get a book too.

I do have a body book, but unfortunately does little to help with sandblasting. Any one have experience with any spot sand blasters. Want to know if the spray guns that attach to my tank work or are just a waste of money. And if so any recommendations so I can finally hit the underside of the truck and possible damages that may occur by spraying on inner fender walls, rails and under gas tanks. Thanks again.
