this was my 1st bondo experiment last year on my project truck, i wasnt planning on keepeing the bed anyway, i used the foam then bondoed over


dif sides of the truck, but same thing on both

 

bout two inches long and 3/4 to an inch tall

rusted out, i thought of using that expanding foam, but worried about it attracting water, fiberglass sounds like it should work under bondo, and that area don't have to be exactly perfect, its getting bedliner, its the fender 'flare' if you can call it that

 

I have the same problem on my ram. same spot and same size. gonna fix it this winter. i plan on using bedliner over mine too. how would i go about doing that though. just put it over the resin or primer then put the bedliner on? any help would be great

 

New technology has come up with bonding agents. A DIY guy can do these types of repairs at home without the use of a welder. Simply cut out the old rusty metal and bond on a new piece of metal.

I laugh at the foam method. That is a big no no... and a complete waste of time and materials

 

Thanks for the info. how do you bond the new piece in. do i just get new metal cut it to size then lay a coat over it or what. thanks for the help

 

Would this metal work for the bottom edge of the door? Got the infamous door rust, and it's movin up the door FAST.

 

I was told that it is really hard if not impossible to weld new metal to that. idk if that is true though nothing is impossible for a dodge fan. lol. um mine is the same way i was wondering that too.

 

Its basicly a glue. Cut patch panel, apply glue, instal patch and let dry. Skim with filler/putty/primer/finish coat.

or google auto body panel bond

 

Thanks alot WaynesWorld ill do that. Rust is a PITA hardcore.

 

Ok first off, never use fiber glass and resin on metal. It doesn't stick worth a crap. Its ok...on plastic/honey comb and stuff like that. I have used the expanding foam trick, but it was on a truck we were selling at the shop and I was 14. If you plan on putting bedliner over the metal, then why not just weld in a new panel? You dont have to worry about show quality paint, if you can spot weld with a 110v mig and have the panel, why not just fix it right and quit waisting your time??? And if you are going thru all the trouble to cut and replace the panel, why would you put glorified JB weld on your truck??? Weld it, sand it down, throw some body filler on it, block it, primer, and paint it. Body work is one of those things that there really isnt any quick easy fixes. Go to the salvage yard, pick up a $5 fender and practice. Fix your truck right and be proud.
