Primed insides of the W-816 and W=818 push rods. Stuck the rattle can in one end and spayed until primer was running out the other end. Then turned them upside down and swirled around. Hard to tell if everything is covered or not, but did make a bit of mess—not to mention the fumes from the primer. I have decided to have the end pieces of the W-818 welded to the small pushrods-want to avoid any possible rivet issues.
