i've been out of body work for about 20 years ,and with all the new ways of doing things and new materials i have a question. what do i need to do to galvanized metal to get fillers to adhere in the old days we had to pretty much grind all the galvanize off to get any thing to stick?

I usually grind galvanized metal the same way I grind bare steel. I use a 36 grit disk on my angle grinder to clean and texturize the surface then apply my filler. Be sure to press the filler into the grinding scratches so that it makes a good mechanical bond.
