So i just bought 2 Stinger voltage meters for my XS batteries to keep tabs on the volts and i am hoping to mount them on the side of the dash in my ford ranger. i dont have the tools or skills yet to do a whole fiberglass mold so i will be using a dremel to cut out 2 square holes to flush mount the 2 meters. the system i am getting will be hitting at least 140db so i need to figure out what adhesive (or whatever else i can use) to keep the meters stuck to the inside of the dash panel without having to use fillers. anybody got any advice how to keep these things in place?
