3M Windscreen Sealer 08509
Discussion
Does this stuff actually set?
I understand that it remains soft and flexible, but so does regular sealant, it's also non-hardening, but I took that to mean in the sense that it won't go brittle or crack.
The product information refers to a "tack free" time of 40 minutes and a "cure" time of 24 hours, which suggested to me that it does actually set in some way?
I think I've used it for the wrong application, it's not curing, it's staying gooey just as it came from the nozzle. If it's supposed to stay gooey, then I've made a mistake (and I wonder why they say it "cures" in 24 hours?)
Thanks.

What have you tried to do with it?
3M Technical Data Sheet says '08509 is used for sealing between windscreen rubber gaskets and glass and car bodies'.

I've tried to use it to fix a bright trim surround around my rear windscreen, which is usually held in place by a series of both clips and sealant, it wasn't possible to fix it in the same manner. I thought it would cure a bit like a silicon sealant but without being too much like an adhesive silicon. If the stuff doesn't cure and stays gooey forevermore, I'm going to have to remove, clean up and start again, with an adhesive I suppose.
Sound like you need an adhesive type. This is not suitable.
08509 would be perfect if you have the old type windscreen which is mounted in a rubber gasket to seal the rubber to the car body & to the glass - my '86 RRC would be a suitable use.
What ad said it skinned over & cured as the ones I've found on a brief google say the same as the 3M.

I can call them but it'll be Monday now. I just need someone who knows the stuff to say it stays gooey or it will cure with time (it's been 24hrs now).
It's going to be a pig of a job to remove and clean up to start again if it does stay goo. I've just run a thick bead out on some card and will leave it exposed, see what happens.
Thanks for the interest at least paintman

Be interested to know what the bead you've put on the card does.
Try 'Clutch and brake cleaner' to see if it will clean up the mess.
I use a lot of it to remove adhesive left over after removing caravan decals & car badges. Does a good job on tar spots too.To date I've never had an issue with it attacking paint but as ever try it on an out of sight area first!
Used with paper kitchen roll.
