Mixing Small Quantity of Hypalon Cement

[a64pilot]

I just yesterday glued the oar clips back on my dinghy and did one or two loose seams. Seems my Hypalon is lasting fine, but the glue is beginning to fail, especially where the plastic bits adhere to it.
I used the 25 to 1 adhesive, Polymarine and it had first coat thin, wait 30 min, second coat 5 min or until tacky.
Pot life though is four hours so no problem at all with four hours pot life you can do a lot of work, max strength though isn't for several days. I have mixed with a syringe before with no problems, this time I was going to use a scale, but the little bottle apparently only holds about 2 grams and my scale only goes to 1 gram so I ended up mixing by eye, seems to have worked well.

I've noticed that we have numerous mixing instructions and recommendations. Several prep recommendations.
However , I believe no one has mentioned any brand of inflatable.
Do we assume all hypalons are the same?
What do all the manufacturers recommend ?

This was recommended to me:Sailrite - Fabric, Canvas, and Sewing Machines Since 1969
I used on my 1984 Avon and it seems to be fine. Is the key in the prep? Cleanliness near godliness so to speak ?
What's the difference between the 1984 material used compared to today's materials ?
Thank you.

I've used Rema products extensively for all kinds of inner tubes. Very reputable products , imho.

SS2000 is the adhesive I mentioned upthread. It is indeed robust! And, FWIW, I've used it on tropical beaches in high humidity, not let the priming coat dry as long as they advise, used trichlor as cleaner and thinner... generally not followed their rather detailed procedures... and damn if it didn't make durable patches on very old hypalon dinghies.

Good stuff, but sadly it does not bond well to PVC, and now I own a pVC dink.

Another + for Rema Tip Top SC 2000.
Not only a great adhesive, but when I was buying it 20 years ago it was a lot cheaper than others.
