Hey its summertime and I cant think of anything I'd rather do than fix
the seam rust on my Syncro!!

I took off my interior panel behind the drivers seat in my vanagon today
and there appears to maybe be a haze of rust along the seams ina few
places no real rusty spots but looks like maybe rusty moisture left a
residue... So do I spray rust preventative or por 15 on these seams.  I
know on the outside of the van were the rust is cause the same thing is
happening there but with much clearer indications of where there is
definitely rust.  Open to suggestions.....
