What on Earth does "a nil pH factor" mean? pH 0 is very strongly acidic, pH 7 is neutral (in aqueous solution at standard temperature and pressure). 131.111.228.219 11:45, 4 December 2007 (UTC)[reply]

I assume that since I have never gotten chemical burn from a plastic campaign sign that it would be pH 7 rather than 0. I changed the word nil to neutral to make the least impact on the article while addressing the ambiguity. Quickmythril (talk) 10:25, 5 January 2008 (UTC)[reply]

No History

There is no indication of when this product was originally produced and began to be widely used - the information I came to the article to find.

The phrase "The last decade has found its increasing use" is vague. This article was written over 10 years ago but there's no indication what decade is referred to.
