OK. Down to my Knee pads here, minicell foam.
Ive used Regular Contact Cement and it has worked fine...but....I have learned that "waterproof" is the glue of choice. I dont want to do it again ...ever...so... Is it OK to use the "water resistant" or is it best to get the "water proof".
sheesh...details details...
Thanks in advance!

what are you gluing down to?
i have begun to use the 3m super 90 contact cement in an aerosol can, and have had super success in kevlar boats, and in plastic c1s. as well as in a esquif vertige which is the abs. so thats my 3 cents.

hmm, that would sure help replies!!! Its an ABS Hull.

Ive used the "Weldwood" water resistant, I believe, in the past. I just fried my brain on MEK about two days ago so it aint working so hot lately, lol
I saw a guy used PL waterproof c.cement. I like 3m products, always good.
thanks again!

Weldwood in the red can works the best. The 3M spray stuff is great for parking lot mods, but can last a surprisingly long time, too!

yeah i am a very lazy person when it comes to getting things done, and the aerosol def. helps expedite things.
i havent had any of my stuff lift, some stuff has been glued for 9 months.

then you did it wrong. I always go with 2 coats on both surfaces, letting them both dry completely. I then heat up both surfaces with the hair dryer or heat gun and whap them together. When my minicell to ABS glue jobs have failed it is invariably my error, usually going too soon.

I have never used but am interested in this spray stuff. Tell me more; brand name etc. Is it generally available?

I use Loctite Max Strength Headliner Adhesive #37312, here in Canada it's available at automotive and industrial supply stores (Brafasco) it comes in a 16.75 oz. spray can. According to Loctite it's water resistant, but after using it for a few years and never have a foam pad come off, I would call it water proof. Easy to use and works great.

martin a.k.a. the great gonzo!

the spray stuff is the 3M super 90 adhesive, its a green and black can available at a general hardware store. i can go look at the can for a product number if you wish, but its abut 15 bucks for a 20 ounce spray can, and its awesome.

I used 3M "Insulation 78" - I sprayed some temporary outfitting into my ME October a year ago - it's still there...

yeah, i have seen both in the hardware store, and never really stopped to look and see what the difference is. the 90, and the 78, but they both seem to work very well. i think there may be another one, i just used the 90, as it was recommended to me.

well i used the 3m super77 spray and everything fell apart very quickly...so....
don't use super 77!

anyways, i kind of prefer to brush on the glue. i got that spray all over the inside of my boat...

i wonder what the numbering means
i have never used the 77 stuff,
cheers

After painting on the Weldwood, it's important to sniff the fumes from both surfaces. When you can't smell the fumes anymore, the surfaces are dry and ready to be pressed together, or you're unconscious and possibly brain damaged, or both.

are from acetone or maybe that two part plastic epoxy. Why they were so strong that after repairing my Rival I went and voted Republican!
