Belzona is the best!
 

I work on ships where cracked blocks, boiler holes, you name it have to be repaired at sea. The Devcon line of products are good. We use them in low stress areas as Devcon is cheap. For "We at Sea", Belzona is ABS and DETNORSKE approved for such repairs (the alternative is replacing the parts). In many cases, it sets harder than the metal you are repairing. It can be filed, ground, and polished and is essentially liquid metal. I don't know where you can purchase it outside the maritime industry. I had to check the spelling (thought it was called Balzona) and they do have a website. It comes in a small pearshaped container and is sold by weight. It's not cheap stuff. If you have a job (like plugging a hole in a crankcase) and don't mind the expense, It's a permanent fix. Good luck Smitty

4th metal repair material
 

Thanks for the information Smitty,
Thats the 4th trade name to be listed here; I have found the Belzona webpage but I haven't found anyone that sells it to the public, other than one "offer to sell" on ebay UK and, as you say, it is very expensive = £36 for 1 Kg and still bidding on that item.
(For each of these trade products I have done a quick search to see if the public can get hold of the product).
There are lots of webpages that offer repair services based on using Belzona but not one that sells the stuff; understandable because those services are like your job - specialist and heavy industry related to Maritime, Oil and Construction applications and the like. As for some of the other tradenames here, there is a wide range of types of "Belzonas" as well; liquid metals, protective coatings etc. I guess if anyone gets hold of some, they should read the instructions and applications list carefully!

I did some footwork for you and you're correct. I can't find anyone who sells the stuff to the public. I order from "Mariners Annual" but you need a password to get in to the catalog. I don't have one. My company takes care of that. The Belzona website gives a phone number in Harogate, UK as a distributor. Another thing you can try (I just did) is search "Ship Chandelers, UK". It gives a big listing of Chandelers throughout the UK and if you tell them what you are trying to do, they might be able to help you. You'll find that the maritime industy world wide is quite an exclusive club. Good Luck, Smitty

I'm doing OK Smitty 'cos I am not actually doing any repairs at present!
Touch wood etc etc.

I was interested in getting some info together about what works OK (and anything that does not, but no one has come up with examples of that so far).

I've come across a good case here of using JB Weld:-

I think it would be useful to get any cases of these repair materials where they fail to perform well; perhaps fall out or otherwise fail after some time.

Walkabout,

I just got a fresh chance to try another JB weld patch on my XT's case. I was riding trails at our local OHV park and my XT decided to ride me around a hairpin turn. (I wont mention the tree root I failed to miss). Any ways, my shift lever made a nice little crack in my lower left case. Very tiny and just barely seeps oil out.
I did pretty much the same repair, but instead of draining the oil out of the bike, since i had just filled in with $15 worth of oil, I leaned it over and pushed some black silicone HI-Temp RTV into the crack. I let this set up, re-cleaned the area and then applied the JB Weld, waited 6 hours and applied a light coat of engine paint. I will have to let you know how it hold up. 14 hours so far and no leak.

Aflow,

The stuff your talking about is called "PIG Putty". Looks like two different putties, one wraped around the other. roll it between your fingers, stick it on, and next day it is harder then hell. My work uses it to fix Locomotives.
