Anyone ever use the weather boot seal for the caliper pistons?

Had to split by caliper today has one of the brake pins was stuck. Still won't come out yet but I have it soaking in WD40 and will try a couple of things tomorrow. 
Figured, I might as well take out the pistons, clean everything up and replace the seals.

Bough this set but then I noticed at the end of the listing it says "If you require the weather seal with the boot on please let me know other wise I will send as in pics"



I'd seen this set earlier but it said was only for 1989-1992 bikes. I figured they must have had a different brake with a bigger seal.
But now I'm thinking this must be the "weather seal with the boot".
Anyone ever use it? I'm thinking of trying it as it sounds like it may protect the pistons better.
