Subject: Re: (ET) Welding a deck with
some rust
Car restorers know that if you don't get all the rust out it's likely to
come back. If you have a wire welder a good repair is not that
hard. (Even a stick welder used with finesse could work.)
Fortunately ET decks are made from fairly simple shapes, so after you cut out
all the rust it should be a simple matter to form some sheet metal of
similar thickness to fill the gap. I'd make it a close fit and use butt
welds, since an overlap is an invitation for water infiltration leading to
another rust repair. If you're in an area involving compound curves and
don't mind a bit of Homer Simpson-style elegance, just close the area
with flat sections and straight welds.
JB Weld can also be used, as above - not over the rusted area, but to
bond in a patch. In this case you need a doubler. That's a
strip maybe 2" wide that bridges the joint. The benefit of epoxy is not
in its own strength, but in its ability to bond to another piece that provides
the strength. Make sure the epoxy wets all surfaces of the joint to
exclude water. You can add some insurance by adding some pop rivets
through the doubler to deck and doubler to patch (rivets sealed with
epoxy), which also serves to fixture the whole thing while it
cures.
