Video: Can you really use glue to attach a new quarter panel?

An alternative to traditional welding when replacing a fender? Why not just use glue?

That’s exactly what we did to replace a wrinkled rear quarter panel on our 1960 Austin-Healey Bugeye Sprite project.

Presented by CRC Industries.

Just a bump for the Tuesday crowd. More how-tos are in the works. (And let us know what topics you'd like to see tackled in future videos.)

Can you do this to replace rusty rockers?

The technology in adhesives is fantastic these days.

Somebody show how to replace a 70's - 80's EFI  system with a Megasquirt.

I'll likely be converting my x1/9 to megasquirt this spring, if you'd like to follow along. One of my goals is to run flex fuel/e85.

How good?   I've got fiberglass panels I was thinking of using Dzuse fasteners to put onto the steel body. But bonding seems like it would be neater. 
is it good enough to hold fiberglass fenders to steel body under racing conditions?  The heat from the tires and brakes wind pressure over 150 ?   Etc. 
   Is it reversible?  Another words if a moving body rubs an immovable force at speed and becomes ugly how hard is it to get off and rebound another fender back on?

Modern epoxies are plenty strong. When you hear of supercars having a bonded aluminum chassis, they're glued together. demo video from Dow

For fiberglass you'd have to make sure the epoxy will stick to it.

Body adhesives are supposed to be permanent, removing it is going to take a lot of effort. Go with the dzus fasteners if they need to be replaceable.

Why not?   I am a builder remodeler by trade and also do my hobby car restorations.  The are many adhesives out there that can be better than welding in some instances.  They hold up incredibly.  Of course the one trade I never reallly learned was welding so I did the next best solution I was good at. Riveting works good for me also.  I like sealants and epoxies because my projects are drivers, not concours or high money restores.   I prefer to play in a smaller' sandbox'.  The project is what is important to me.  The end product is just something to aspire to.

Oh boy...   We tried for many months to convert my '73 Mercedes 450SL from Bosch D-Jet EFI over to Megasquirt. Even hired a "Megasquirt guru" to program it, with no success. We could get the car to basically run, but not at all drivable.

Eventually reverted back to the original Bosch D-Jet, and with a little work, it runs near perfect.

BMW has been using epoxies for years.
