Default 3M 5200

I did 3M 5200 with great results. $25 for the tube, more than enough. That is what Todd at Todds' Canopies suggested.

Default Easy...

Fit canopy as normal with clecoes. Once in position, mask off area where you DON'T want adhesive, and the area that you do, scuff it with sandpaper and clean it up with a cleaner that will not react with canopy. Apply adhesive and clecoe canopy in place. Using your covered finger, put a nice filet in adhesive on the top and bottom of canopy skirt to make it pretty. Pull masking off before adhesive sets up. Double check that everything is right and if it is, wait 24 hours and it will never come off. Make sure you use the fast cure, not the 7 day cure. It is paintable too. I have a piece of canopy attached to a piece of 5" long aluminum tubing, and using pliers and a vice, no one has been able to get it apart.

The most common use for 3M 5200 is marine applications below the water line. It is used as a sealer for through hull fittings and such. I would have never thought of using it for a canopy adhesive but I can say from personal experience that is some extremely strong bonding stuff. I recently had to replace a through hull transducer on my boat that had been sealed with 5200 and once I was finally able to extract the old ducer, it brought some of the surrounding gelcoat from the bottom of the boat with it!

Default Flexibilty

Todd assured me Sikaflex was the all the adhesion I would need ( no rivets ) for my RV3 tip up. He said MANY glass EABs use adhesive only successfully.

There have been numerous comments regarding Sika joint thickness to allow some flex for expansion differential. 3M 5200 sounds like it bonds WELL. Is there a flexibility ( expansion accommodation ) parameter we should be aware of ??

There is flexibility in 5200, and should be no problem. Todd was the one who told me to use it, and doing research here has shown that it has been used successfully. My brother works for American Airlines, and they use 5200 when they want to bond something permanently.

The use of 5200 has come up a number of times. I have used it quite a bit in marine applications. I planned to use the 5200 for the canpoy, but after further research, 3M reccomends that is not be used as sole-means for window attachments. Maybe this is just a liability disclaimer, but they do call for a secondary mechanical fastener.

Todd has told me of RVs that have flipped over and shattered the canopies, but the 5200 did not let go. If some one can pull off the scrap piece of canopy from the aluminum tube (5" section), then I will look at adding a mechanical fastener. But everyone that has looked at it (A&Ps, GlasAir builders, etc) has no worries, too include Todd.

My experience with 5200 on a sailboat that was stored in a dry area on its trailer, is that after about ten years, it fails. It's environment was Colorado (an arid state), 4 months a year floating on the water and 8 months on its trailer.

It was used in a couple areas as a hull/deck sealant and to bond a copper lightning strip to the inside (water-exposed area) of the gelcoated daggerboard case. Neither area got any direct sunlight.

When I repaired those areas, I learned that the 5200 really, really, flows when applied. It was difficult to apply to a vertical surface. It might be easier to use strictly as a glue between two parts that are held in place during curing, but without that, it was annoyingly difficult.

3m 5200 is what I have attached my canopy on with, not flying yet. It is definitely bonded well. I don't expect to have any problems. Only hole in my canopy is where the latch goes through.
