I'm spot sanding the bucket of my ST824.  There are some areas that are in need of a filler, such as seams and welds.  I know sharp edges are where paint tends to get thin and be the first place that paint will peel from.

I'm considering automotive seam sealer, but wonder if epoxy would do the trick as well.  Maybe I'm being penny wise and pound foolish.  I hate to buy a 14oz, caulking gun sized tube of seam sealer to use a tiny bit.  I have some paintable epoxy on hand.  I know you shouldn't use anything with silicone in it; paint won't stick.

Any suggestions.

Something like 3M Dynatron Seam Sealer then?

That product will work as it is designed to allow for flex in automotive body panels.  It is critical for any product to work the the surface be free on any rust, dirt or oil and if possible paint.

New Yorker suggestion to lead the seam will also work and it not that difficult to do.  You can buy body solder/ lead for automotive use but almost any solder/lead will work on a properly prepaired steel surface.

you can look at some stuff on Eastwood see the link below.

I When I restored my blower.  I welded some of the outside blower seams.  Used seam sealer on the inside and hard to get to places.  Also used spot putty in some areas.
The seam sealer is the quickest and easiest to use.  It's also probably the best thing to use in this type of application.  It's what it's designed for. 
The welding is over kill unless you doing a repair as well.

I have restored many a hot rod and seam sealer is an indispensable product to have.   I also like to use lead on easy to reach stuff and it is easy to form and shape great for those overlapping seams to smooth them out.  Mig welding works but it a pain to grind down and if you are just trying to smooth out a seam and not do a structurial repair i would avoid the welder.

Expensive but the best. POR PATCH     .POR15.COM.

Yep!  POR15 does it for me.  It's amazing stuff.  Does everything it claims and that the other so-called rust paints do not.

Well, I painted already.  I am going to put the sealer over the paint.  I know it is backwards, but I didn't strip the paint entirely.  Just spot sanding and prime.
