Welding on my dash frame question

@Bodyperson since Ive been out of the trade for awhile, perhaps you could recommend a good metal glue/filler that I could use to make an enlarged hole smaller for retapping of a small screw, one of my hood pin holes, and another where my under the steering column cover fits. JB Weld is the only thing that comes to mind, and I really dont want to weld in those areas if I dont have to.
I use Lord Fusor. 3m, Sem Products, they are all good. We tested the Fusor. We glued 2 welding coupons together and pulled them apart on the frame rack. The metal failed. The overlapped glue joint was stronger. There are glass beads in the glue that significantly reduces the possibility of over clamping the products ability to squeeze out. You can hear it crunching when you clamp it. Adequate clamping is a must. Plastic filler does not like to stick to it.
