I'm thinking about painting my Coronet but, at the moment I really don't want to mess with restoring and installing all the chrome trim. However someday I would like to see it with all its trim on so welding them up is kind of last resort. Is there some kind of filler out there that I could use to fill these trim holes without fear of falling out, cracking, absorbing moisture and bubbling paint, or other ill effect? My body guy doesn't do lead so thats out. What do you guys think? I'm in Kansas and we usually have two seasons HOT & COLD if thats a consideration.
