Gees Dave, I'm disappointed you haven't been reading my thread about my Newcastle caravan project. The words 'bote cote' get a mention on just about every page...  Brilliant stuff, if I may say so.  I doubt whether you can actually sand it back too thin, unless you used a really coarse sandpaper and let the sander run forever. Tough as nails it is. Only 'complaint' I have about sanding it is that it clogs up the sandpaper fairly quickly, so you have to have a dustpan brush handy to keep wiping the powder away from where you are sanding, and brush the surface of the sandpaper at the same time to keep it clean. Other than that, it sands fairly easily if your aim is to just roughen up the surface for painting. cheers, Al. |

G'day Dave, Yeah, the term "Bote-Cote" is really a sort of umbrella name for a number of different products. I reckon the best thing anybody can do, who is contemplating using these products, is to buy the Bote-Cote handbook that explains everything you'd want to know about the stuff and how to use it, and so on. The core products are the resin and hardener. It's mixed in a ratio of 2 parts resin to 1 part hardener. You can buy a "starter kit" made up of 500mls resin and 250mls hardener (and known as the 750mls kit). I bought that one just to get a feel for how it all works. Then I bought the next size up (1.5 litre kit), and ended up realising that wouldn't be enough. Now I'm up to the 3 litre kit.  The basic resin/hardener ratio is used when fibreglassing over timber (eg. plywood boats), or when applying additional protective coats to the timber surface. Then you have the additives that make the resin mix either thinner or thicker. A timber preservative liquid is added to thin the resin so it soaks into bare timber for the first coat. Alternatively, a powder is added to thicken the resin when you want a gap-filling glue. A different powder is added when you want to fill depressions in the surface and sand them easily after curing. All of which means there are lots of different end-uses depending on which of the products you add together. Bote-Cote is available from marine suppliers. I buy my stuff from our local yacht shop, but it can also be bought over the internet (from suppliers such as Boatcraft, etc.). Google your nearest marine supplier and see if they have it. There may well be cheaper resin products available on the market, but what I like about Bote-Cote is the versatility of the product parts. I've put a thinned soak coat of resin mix on the bare plywood in the van (which makes it equivalent to the old "Resply" that was available for caravans in the old days), and then I've used thickened bote-cote as a gap filling glue, and I've used the standard mix for a couple of fibreglass patches. Having all the ingredients coming from the one manufacturer gives me more confidence that it will all work together properly in the finished product. Definitely people should buy the Handbook. Best five bucks you'll ever spend. cheers, Al. |

G'day Dave.
Get your bote cote from Duck flat wooden boats in Mt Barker as we do.
Another Dave from there is reproducing my teardrop .
