5200 for a fiber glass car panel?
 
I have a fiber glass rear quarter panel to attach to a 85 4 runner. The 3m panel adhesive is about $60.00 and the gun you have to use is $250.00! Can this stuff be used to bond a fiberglass panel to a steel panel? Has anyone used 5200 to do something similar to this?

5200 is I believe a polyurethane adhesive. You might do a little research on the panel adhesive to determine what chemistry it uses. It might also be polyurethane.

5200 sets up pretty hard. It may not be necessary to match the mechanical properties of the two adhesives, but it wouldn't hurt. There might be an optimal amount of flex for that joint which 5200 may or may not accomodate.

If you can find out something about the family that the panel adhesive belongs to, you might find a cheaper alternative. What is the part number or name of the adhesive you are looking into?

Remember that if any 5200 is exposed to sunlight it will turn yellow and mildew

5200 sticks to just about anything once its exposed to the Air and the moisture in the air.

Use the 3m panel adhesive
 
I've used the 3m panel adhesive and it is great stuff. If you are careful, you do not need the gun.

As I recall, I cut the tubes [which are connected] open. Then I used a 8" ratchet extender to push out the amount I needed, then mixed them together and applied.

While 5200 may work, it is a completely different animal. The panel advesive becomes very hard while 5200 stays flexible.

I didn't see a part number for the product like the rest have in big letters. It was just called "3m panel adhesive". JP3 when you mixed the to together yourself do you use a certain ratio or just 50/50? The guys at the paint store are pushing me for the gun only because they no its the right tool to use. I also found something made by NORTON witch is about half the price with the gun.

No, not =
 
As I recall the tubes are different sizes. It looked like it was in a ratio of 3 to 1.

All you have to do is push the plunger in each tube down the same amount. I hope that make sense. If you are really concerned, you could push out the amount needed out of one tube, then measure the distance the plunger went down, then finally push the other plunger down the same distance.

It's funny how those supply shops are. When I went to buy my supplies, the guy looked at me like I was crazy when I asked how much the gun was. He was like just mix it yourself...

I am pretty sure the guys at your shop are not just concerned with doing the "right" thing. If they were they would let you "borrow" the gun.

I hope that helps.

I used it to glue the trailblazer logo back on to the side of my wifes car about 3 yrs ago and it's still there.

5200 is some pretty amazing stuff. When I looked up 3M panel bonding adhesives some were Urethanes and some were Epoxies.
