Be a little careful heating the stuff too: the fumes are very, very volatile.

Once had a safety demo at work: the guy put, oh, perhaps a quarter cup of acetone in an empty plastic 5 gallon water jug, swished it around a bit, and had basically built a flamethrower. Impressive gout of flame.

Toluene is very good at reactivating the glued surface when required and that comes in very handy sometimes.

Make sure they keep well away from open flames and smokers. Acetone fumes are pretty spectularly flammable (as are MEK and Toluene, but I wouldn't suggest dipping fingers in either of those, either.)

The effects from all of these solvents are, for the most part, pretty long term. Short term, there's not much obvious unless you suffocate from fumes or blow yourself up. I'd suggest perusing MSDS's (Material Safety Data Sheets; readily available in the US; don't know about the UK), as health effects and safety are the main reason they exist.

You can order on line this is the link MEK PVC Solvant at NRSweb.com
and if you need glue I recommend Sta-bond from the same place is very good and they have instructions on the web site how to use it, this is the link Stabond™ Adhesive at NRSweb.com they ship ground only because this products are HAZMAT and are not allowed on plains.

Toluene used to be available at Ace Hardware, but was not in stock last time I looked. It can be ordered online (I saw no restrictions about shipping to California.)

MEK is pretty widely available: Ace, OSH, and Home Depot all carry it; almost always in quarts. If you need gallons or larger, you may have to go online for that as well.

Mek

MEK is available (only) in gallon sizes at Lowes, in quart sizes at Home Depot (just looked yesterday).

I thought the main problem with toluene is that its been confirmed as carcinogenic ?..

I recently did a repair using MEK for the first time but IMHO thats only for PVC or PU work ? Its very effective but Its probably carcinogenic too .. what the hell .. I had dinner later with a nice malt whisky and a cigar afterwards

I've never used a chemical solvent for a hyperlon repair. We only use MEK on PVC boat repairs. For Hyperlon you just need to abrade the top surface (mechanical clean) so that the adhesive bites in. Using a solvent will not help in the adhesion process. The old man has been repairing hyperlon and pvc inflatables for over 50 years and the process is always the same and works without fail.

As a general rule hyperlon boats will last around 25-30 years if looked after - after this they become porous and air will seep through the entire skin (some people will pay to have liquid latex poured into the tubes and this will give you another couple of years. Whereas pvc boats have a life span of around 15 years, after this the fabric becomes brittle and won't take adhesive anymore.
