Heard a bunch of guys on a bodywork forum swear by the Astro Pneumatic onboard air hammer kit for popping spot welds. Runs about $120 and hooks to your compressor. They say it walks the weld out without drilling at all, so no metal shavings and way less chance of punching through both panels. Been meaning to grab one myself before my next rocker job.

My buddy Dave did injector cups on a 7.3 last spring and went dry like the old timer told him. Two of them started seeping within a month and he had to tear it all back down. When he redid it wet they sealed up fine and that truck's still running around town.

My cousin did something kind of the same but with a rental property, she passed on a Section 8 tenant with guaranteed checks to keep a guy who paid cash and never bothered anyone. He ended up staying four extra years and fixing the fence himself, which saved her way more than the guaranteed rent would have brought in. It's hard to know if it's luck or just good karma, but I figure treating the people already in your corner right tends to come back around more often than not.
