nickel spray

Hi Daniele
		Like I say, the nickel spray tends to peel off the outside
of the bottles. I use foil again. I've discovered some good heavy duty
aluminium foil for cooking. It's unbelievably thick and feels more like
lead foil when you are wrapping it up. I now seal the bottles solid
with silicone, but I leave a good couple of inches air space above the
oil layer for possible expansion although I've never noticed any
increase in the temperature of the contents after prolonged use.
(I've often run coils for 5 solid minutes).

Hi all

what about using this spray only outside the bottle ?
one can water sand the bottle and spray it  on the outer surface.
this way you have half the goods and half the bads

just my cent :)
