It comes with a caution : Results may be addictive

First tried it on an aluminium dinghy rail that looked pretty scungey, and holy cow the caution is correct - next rail !!
Got me brother to get me some at a particlular truck stop in Marulan, and the temptation got to him before he could hand over the bottle, it's not quite full . It is pricey but seeing results - who cares >> $20 + GST. Seen it on the 'net for nearly $40 tho, beware!
As name suggests , it is purple in colour in a clear bottle 355ml
anyone else discoverd this stuff - made in USA ?
