That applies to all products. For example a 16oz bottle of wheel cleaner is $14.99, the new 32oz size is $29.99 (on sale for $24.99 currently). Double the product, double the price. Makes sense, right? So if you're selling a 16oz bottle of paint correcting polish for $29.99 and decide to shrink it down to half the size at 8z, the price should be adjusted to half accordingly, which is $14.99. The $5 price hike to $19.99 on the 8z products doesn't make sense to me at all.
