<BR><BR><FONT face=sans-serif size=2>Are you crazy-mon? First, the bottles are
Polyethyl tera phthalate....and are NOT chemical resistant. Let me
provide and example that I know you can understand....BEER.</FONT>
<BR><BR><FONT face=sans-serif size=2>Whether you realize it or not, beer has
alcohol in it. Alcohol is deemed in some parts of my industry as a "solvent".
Other view it as "essential", but thats another story. Until very recently,
did you ever notice that beer NEVER came in plastic bottles? Even now only
beer without any real taste (its raining beer!) comes in plastic, so they can
sell the stuff up north where the football fans like to throw things at the
Dallas Cowboys. Shrinkage comes from one of two things, first you swam
in the cold water way too long, or second you leached out what is reffered to
as a "plasticizer". A plasticizer is an additive that allows the grocery store
idiot to drop that bottle of coke without explosion. It also is the stuff that
you just ran thru your engine. When it croaks, or when your glow plug croaks
you will now have an obvious reason.</FONT> <BR><FONT face=sans-serif
size=2>Beer uses ethyl alcohol, we use Methyl, which is much more aggressive
as a solvent. Our real fuel tanks are made from polypropylene, which is VERY
chemical resistant in is un-plasticized form. As a matter of fact, if you buy
Methyl alcohol, it comes in polypropylene drum, because it will corrode steel.
As a matter of fact most fuel comes in polypropylene containers.....ones with
steel cans have an epoxy coating in them.</FONT> <BR><BR><FONT face=sans-serif
size=2>And now to debunk another myth........the above plastics are
"thermoplastic" epoxy is "thermoset". Epoxy (thermosets) does not get
brittle with age, unless you the user add some crap to it. 5 minute
stuff WILL as it is accidently plasticized by all the stuff used to jack up
the reaction.</FONT> <BR><BR><FONT face=sans-serif size=2>And one last
thing.......... Beer + Plastic = bad taste, and as my Chemistry 101 professor
so diligently demonstrated in mathimatical terms, you should never drink light
beer.....Instead, drink a real beer, followed by 10.52 ounces of water, then a
real beer and another 10.52 ounces of water. Your caloric intake will be the
same as 4 light beers, but at least you got to drink 2 real beers.
