Re: Frame stiffeners w/ 3m panel adhesive a terrible idea?

For panel adhesives to work, the stiffener needs to sit flush to the existing unibody frame rails.
I have installed two sets of stiffeners and neither fit tightly without needing to be persuaded into close contact using floor jacks and c-clamps.
This would be next to impossible to do just using an adhesive unless it has large gap filling properties, while still retaining its full strength. Prepping the metal for the adhesive is another set of problems to solve.
Even if you solve all the above problems, you still have the cost of a large amount of expensive adhesive to buy.
It could be cheaper to prep the metal yourself and pay someone to weld the stiffeners in.
