Keeping the solution moist if used in direct sunlight during the hottest part of the day may be a challenge. The product is formulated to minimize drying as much as possible. We were initially concerned drying may be an issue. Based on the feedback we have received from people who have used Spotless Stainless (many in South FL) keeping it moist has not been an issue. We avoid cleaning stainless in direct sun during the hottest part of the day (I want to be somewhere cool anyway).
When we clean our stainless we have a small container of spotless stainless in hand and walk around applying the product with a brush. If we see an area that looks like it may drying we lightly re-brush. It is a very simple process and takes very little time compared to methods that require rubbing, scrubbing or polishing. Effective rust removal and extended time between cleaning with minimal effort and mess were the drivers for us to find a simpler method to remove rust and protect our stainless steel - hence Spotless Stainless..
A funny quote from a user posted on the CSYForum "The best thing I like about it (Spotless Stainless) is,,,you can stand on the dock talking to your friends and drinking a cold one .....and one fellow says " hey I thought you were going to clean your SS today?" and you can reply..." I'm cleaning it as we speak!!!"....priceless ...."
Time is related to temperature. The warmer the better your results in less time. So it may not take 30 mins to get desired results. We use the statement up to 30 mins. All of this is discussed in our faq at FAQ - Spotless Stainless Removes Rust, Protects Stainless Steel

Lancelot Spotless Stainless should adhere to your shaft and stay moist without the need of a rag (if not used in direct sun during the hottest part of the day). It is formulated to adhere to vertical surfaces so it should stay on your shaft. The thickness basically provides a media for a suspension that is like placing your stainless in a bath. We use it on our stanchions both horizontal, vertical and the base on the deck - It works..
