About the same thing for me too. I have hundreds of pounds of lead shot from my hand loading days, mix it with epoxy and poor in onto something like the cowl, make molds and do the same, make molds and melt it into the molds. Stick on tire weights work great and I have double sided tape so I can use it over and over. I always try to move the battery pack around before I ever use lead but over the years I use what I have. As long as it stays put your OK.
