When Replacing a fender on 1999 dodge Dakota is there special glue the manufacturer uses that requires tool when taking off?

No, Dodge Dakota fenders from 1999 (and most cars, for that matter) don't use special glue that requires a specialized tool for removal. They are generally attached using:

* Screws/Bolts: These are the primary fasteners.

* Clips/Fasteners: Plastic clips hold the fender in place at various points. These can sometimes break during removal.

* Body sealant/adhesive: A bead of sealant is often used to help seal the gaps and prevent water intrusion. This is a flexible sealant, not a strong adhesive bond that requires specialized tools.

You might need a few tools to remove the fender, such as screwdrivers (possibly including a Torx driver), pliers (to remove clips), and maybe a putty knife to carefully separate the sealant. But no special glue remover or specialized tool is needed. A standard plastic trim removal tool kit will help protect the fender and aid in the removal of clips.
