Yep, it has been working miracles for me! I have just about finished up my Gran Sport since the beginning of the year with this philosophy.
Today the pump looks clean! WHOO HOO, of course I am saving real celebration for a few more days. I did put the top down and removed the mouldings around the top on the quarters that I had neglected to put the clips on! (insert rolling eyes smilie) I didn't find the clips when I put the mouldings on back months ago and figured it didn't use any as it "sort of" held on nice. But after MUCH fight out there this morning (what a STUPID design!) the moulding is in properly and I am thrilled.
Now for a walk with the family along the SF bay and keep an eye on that pump later tonight.
