Exterior panel glue

[rkainsworth]

I have a 99 Adventurer...exterior panel around rear wheel has come detached (appears to have been glued) to support. Anyone know what kind of adhesive this is? Rich

What are the materials you need to glue?

Can you provide a pic of what needs repaired?

I assume outer skin is fiberglass and inner frame is metal

Securing fiberglass to metal can be done with 3M 5200. It comes in regular and quick cure, either in a squeeze tube or caulk tube. I have no experience with quick cure version, but I am told it has less strength. I do have lots of experience with the regular version of 5200. I assure you the metal and fiberglass will never come apart. Note.... the regular version does take a week or more to cure completely.

Clean both surfaces and use 3 M red double sided tape, easier to work on if you take the panel and frame off your coach

Another product that can be used is SEM 39537 Weld-Bond Adhesive. It's used by body shops to adhere fiberglass and plastic panels to metal substrates.

Here's a quote from their MSDS sheet:

Description

39537 WELD-BOND ADHESIVE is a non-sag, two component methacrylate adhesive system formulated to bond metal surfaces without the use of an external primer. 39537 provides long working times (45-60 minutes) allowing body shops to correctly position parts for proper alignment. This adhesive contains glass beads to insure adequate bond line control. 39537 is an easy to use 1:1 adhesive that forms resilient bonds and maintains its strength over a wide range of temperatures. 39537 is suitable for bonding a variety of substrates especially automotive grade cold rolled steel. Recommended substrates include steel, galvanized steel, e-coat, aluminum and stainless steel.

I used it on the hood and a headlight bucket of our 2001 Adventurer in 2007. Everything was still holding fine when we traded it off in 2013.
