Will regular applications of prufhide guard against damage to a Brooks B17 saddle, from rainwater, please?

That's what it's for showerproof really. Never Proofide a wet saddle. From the Brooks website,

"A new saddle should be treated with Brooks Proofide leather dressing to help assist the ‘breaking-in’ process. Proofide keeps the leather supple as it is specially formulated from natural ingredients to condition, preserve and shower proof your saddle. Proofide is the only substance that should be used to care for your Brooks Leather Saddle.
Apply a little Proofide to the finished side of the leather. Allow the Proofide to permeate until dry and then polish off. Proofide should be used several times during the ‘breaking-in’ period and every 3-6 months thereafter. On bicycles not fitted with mudguards, an initial application to the underside of the saddle will be beneficial, this needs not to be polished off. The leather gets its colour during the tanning process and it is possible, therefore, that some colour residues will remain. It is recommended to polish the saddle with a soft cloth before first use."

IT will and that is what its for, just like shoe polish though it will give out undera constant soaking SO carry either a brooks saddle cover, plastic bag or shower cap for when stopped. I use one of those plastic shoe cover you often see at swimming pools to stop oputside shoes contaminating floors
