Contralube770

Seems I might have started a chain of events causing one trader to sell 60+ and another to sell 143 overnight. Ooops. Still, my friends got about 15 or so between them plus those sold after I revived the post. Sorry to those who missed out, I managed to get a couple prior to posting.

Regarding comments about Vaseline. I have actually used Vaseline on battery posts prior to putting on clamps and it does work quite well. I clean the lead until it is bright, smear on a small amount of Vaseline and wipe off excess. Last time I used it on a bow thruster battery the posts were still clean a year later and no sign of arcing.

I tend to use a litle silicone grease to minimise corrosion on non-electrical gear and use Contralube on the electrical stuff.

Vaseline is many times better than using nothing if I don't have any Contralube. Petroleum jelly is hydrophobic and also excludes oxygen so battery posts don't build up a non-conductive grey oxide layer. It doesn't conduct very well (less than rubber or some plastic) but is easily squeezed out of gaps to allow metal to metal contact.

So not perfect but a reasonable substitute in some cases if you are stuck. I think that it also woks reasonably well if you run out of thermal grease for a CPU mount on a PC. I think that some people even smear some on their lips for some odd reason. :D

I checked eBay on 27th as a baseline and found only one seller. He was out of stock, hence the £800 cost per tube.

There are 2 new entries now and both are auctioning tubes with bids starting at £14 & £16 pounds respectively, plus £3 pounds delivery. Not a bad profit if they did buy up up the old stock.

My advice is to bid up to £25, that way you get it half price. And no, I'm not selling any :)

One of the sellers has the tubes on their own website at £25 + £3.50 delivery. I spotted it when looking for my last lot, so assumed they'd had new stock for a while. I wonder why they are suddenly offering it on eBay. Perhaps they managed to find some old stock and guessed people might be looking for it on eBay for next few days.

I know the seller on the site won't promote this himself but as there is this buying frenzy, and his site won't show on google yet... http://www.newboatgear.co.uk/
Check the 'Products' menu item.

I can understand the "frenzy" at £8 per tube and "lot of interest" at £10-£12 per tube. However, prices have jumped to £23-£28 so imagine that things will calm down. Last of old stock will vanish and I imagine that prices will settle. I think that new price for 25g is around £14 so that makes 25g around £40 + del. (assuming larger size is sl. cheaper per gm). Nigel might have a better idea of the current price for new stock. I'm assuming that he thinks ~£50 from earlier post.

I had a look at the above site and it is under construction with relatively few items. I imagine that the Contralube was acquired fairly recently (otherwise he'd have sold it at £8-£10 by now before relising the price had jumped). No doubt things will pick up a bit but don't think he'll run out of stock overnight.

I assume the owner is linked to owner of http://www.allproductdesign.co.uk as both are non-trading private individuals registered by non-companies (as far as I could see). Sounds like an interesting person from the description. I can relate to a Chemical Physics degree having studied Chemistry, Physics and Computing. I can absolutely guarantee to be hopelessly out of date now on all 3 subjects. :D

Looks interesting and I'll keep note for time my Contralube runs out. Either that or consider making all connections out of solid gold, might be cheaper if Contralube prices keep zooming up. :D
