Does 914 rubber sell the recommended adhesive for gluing the vinyl to the sail panels.

DO NOT use Gorilla Glue in a spray can. I used it on the dash board in summer, already pealing off in the cold.

I prefer to use Wurth high temp spray adhesive.
We will be stocking it soon but are not there quite yet

I"ve always used 3M Super Trim adhesive. Just don't try and glue the whole thing at once.

Carefully position it and use some masking tape to hold it, as well as masking off the entire area so you don't get adhesive where you don't want it. Then fold the top half down and spray both surfaces and let it dry the time listed on the can. Gradually smooth it up from the glue line working back and forth smoothing as you work your way up. Then fold up the bottom half and repeat the process. If you try and stick it all at once, you'll probably get a wrinkle or air bubble

While I’m not experienced at sail panel adhesion, my $.02 on the 3m is it will eventually fail with a situation that sees a lot of sun/heat. I use a lot of 3m adhesives (90, 94, Fast Bond 30) in my profession and they seem to always fail after several years in outdoor applications. IMO they do not withstand the temp extremes that a sail panel may be exposed to. Again, just my opinion and experience with various applications using contact adhesives outdoors.

Will you glue over the paint or sand it down first? What's the preferred install?

Factory I believe, glued over primer surface, that was splashed around the edges with body color overspray. I’ve used this over the years, with great success, or any good quality rubber cement.
Register the sale panel material to the panel, apply glue to both surfaces, completely, and let dry, then adhere.

I would say, as above with the Wurth, any old school, solvent based, rubber, contact adhesive would be your best bet. Proper adhesion to both surfaces is the critical aspect. The sprays bond to themselves well, but let go from one of the substrates under extreme conditions suck as heat or continual temperature cycling. 3M fast bond 30 has given me the best results as it a rubber based contact, but still questionable under extreme conditions. Older solvent/rubber based contact adhesives bonded to various substrates much better, IMO. I’m not really sure what’s available outside of California though. We only get stuff that pregnant sea turtles can eat without being harmed.
I would also go with at least a Scotch Brite scuff sand to help the bond.

Again, JMO

This is a great vinyl adhesive and not affected by heat cycles.
https://www.amazon.com/HH-66-PVC-Vinyl-Ceme...230&sr=8-13

also has a thinner available to shoot thru a spray gun if you choose.

Stay away from the spray cans

I understand the eco dilema with spray cans, but I can tell you that the home mechanic with limited experience will have better results with a spray, than brush on. It's easier to get it nice and smooth with a spray application, and easier to get lumps with a brush on. You can guess how I know this (IMG:style_emoticons/default/smile.gif)

My upholstery guy who is the local Porsche club guru says most people who have failures, are using too much.

Just did this a few weeks ago with @SocalAndy and his method is to scuff the paint with a Scotch pad for adhesion.

Weldwood landau top adhesive. Withstands high heat. Unfortunately you can only buy a gallon...but it's worth it. Great for seats, dash tops and sail panels. Use a cheap HF spray gun and wear a respirator. Amazon link below

Great discussion on this, thanks.I’m getting ready to redo my sail panels as a winter project.
My take away is not to use spray adhesive and scuff sand prior to gluing.
I’m pretty sure I’ll use “ Worth”
