A welder and an 8 lb sledge belong in those spots.
lol won't find either one out in my garage. Duct tape is for duct work, and WD40 is for the birds.Funny though!

To provide lab data about which sealants and tapes last, and which are likely to fail, research was conducted at Lawrence Berkeley National Laboratory Environmental Energy Technologies Division. Their major conclusion was that one should not use duct tape to seal ducts (specialty tapes are available for this purpose). (They defined duct tape as any fabric-based tape with rubber adhesive.) The testing done shows that under challenging but realistic conditions, duct tapes become brittle and may fail.[6] Commonly duct tape carries no safety certifications such as UL or Proposition 65, which means the tape may burn violently, producing toxic smoke; it may cause ingestion and contact toxicity; it can have irregular mechanical strength; and its adhesive may have low life expectancy. Its use in ducts has been prohibited by the state of California[7] and by building codes in most other places in the U.S. However, metalized and aluminum tapes used by professionals are still often called "duck/duct tapes".
WD40 is pretty flammable too. Back before PB blaster was heard of in my area I was using it to lube drill bits while I removed a damaged freeze plug. Shot a squirt on the plug and it burst into flame all by itself.
