snaps, zippers, Velcro

Hi to all,
I'm not a big fan of zippers and less so of snaps. Has anyone ever used Velcro for a fly-bridge enclosure?
What would be the good and bad points.
Thanks

I have not had good luck with Velcro in a UV environment. Bungee straps might be an option. Not sure of your application.

Iíve never used Velcro in that application but if I was going to try it, Iíd use 3M Dual Lock instead. It uses 3M Very High Bond adhesive and it grips to itself stronger than Velcro. https://www.itapestore.com/12-x-2-SJ...yABEgJY5PD_BwE

I have used Velcro on boat canvas but only to kerp flaps closed and prevent wind driven rain leakage.
Ihave found that even in short NE seasons the vrlcro only lasts a couple of yrs.
I do not promote using it but will do it where prior psnels had it and customers want it.
I have had many requests to repair pickup tonneau covers where the velcro has failed.
I would strongly suggest rethinking ypur position but you are the customer and get to make the decision.

Are you thinking velcro on fiberglass & windscreen to eliminate snaps and top & sides to eliminate zips?

What are your objections to zippers... the most common closure.

3M Dual Lock claims to be UV resistant.

In wind and driving rain, I don't believe Velcro would hold. Snaps and zippers have better holding power.

I have used dual lock and it's great. Don't know if there's a version of it that can be sown to fabric. As others have said, Velcro doesn't hold up very long when exposed to UV. Perhaps if it was covered with some kind of flap?

Love velcro in the proper application. Using it in place of snaps or zippers isnít the proper application. It will not hold on its own in a strong wind. +1 on the UV deterioration.

I once fastened it to heavy fabric with ss pop rivits and backing washers.

Thanks for all the info. I had thought of replacing zippers on the fly-bridge canvas when they failed.
Although I wasn't ready to do anything yet I am glad I asked.
Thanks again

I hate snaps and lift the dots use twist locks instead.

I use twist locks on high stress points and at some corners to hold the panel in place and then use regular snaps in between. I don’t use twist locks where they will stick out and get caught on you when passing by.

How do you get zippers back together when they are just a little bit short from elements? Glass will not meet and leaks are result. It is making me crazy!

If you truly canít get them to come close enough to zip, then you may be able to move the zippers closer to the edge of the panel. Downside is that the zipper will be more exposed to UV. But it may make them work until it is time to replace the enclosure.

Velcro is almost as bad as silicone.

Agree w Commodave - moving zip may work.
Also take a look at EZ-XTend zipper extenders
https://www.canvas-boat-cover-and-re...t-zippers.html
I haven't used them but they look interesting and work as a stop gap solution.
If anyone has tried these I'd appreciate any comments.

I have used the EZ-Xtend zippers and they work well. They add about an inch so the gap needs to be severe or you will have loose canvas.
