Would appreciate any advice on how to treat braze welds. I braze weld my patch panels/skins and always use wire wheel attachment to clean the weld and use metal prep to clean. Anyone know of any special cleaner or etching solution that is specially formulated to treat welded steel?
what about por15 metal prep... hmm. just a suggestion
Ask your paint store if the brand of metal prep you're using will treat brass.
I would recommend switching to a silicon bronze rod , and getting away from brass , as bondo and some new primers will let go of brass in time , yes even preped right .Quote:

Silicon Bronze still has a low melting point , and has a better weld strength then brass , and will still give you less metal warp .
GM has used Silicon Bronze for many , many years , the roof to C pillar and roof to A- pillar welds were all Silicon Bonze , and people always thought it was brass.

There is some kind of reaction between the steel and brass and flux. I never was able to get a lasting repair with brasing. I think the only thing that worked for me was mig welding.
