McKee’s 37

I love detailing my coach. And I love great products that help make detailing the coach a joy.

I came across McKee’s 37 products back when I first ordered my motorcoach from Newmar. I was looking for RV specific products and eventually wound up on the McKee’s 37 RV website. What impressed me was that the founder, Bob McKee, is an avid recreational boater and a Newmar owner:

I’m blessed. Plain and simple. Not only am I fortunate enough to call the sunshine state home, I’m the proud owner of a Newmar motor coach and a 21 foot Cobia center console. With my 30 plus years in the surface care enhancement industry, it was only natural to develop a product line tailored specifically for the unique cleaning requirements of boats and RVs.

I was surprised to discover that my latest undertaking would be so much work, and I was also surprised at just how much fun I would have developing the entire line, from the high-sudsing Carnauba Wash & Wax to the hugely capable All Purpose Surface Cleaner. I thought it would be a walk in the park, because there are a lot of marine and RV products on the market. It was my goal, or mission as my senior chemist likes to call it, to make my line of marine and RV products superior to anything else available. What my team and I developed is so good I decided to put my name on it. Enter McKee’s 37 Marine & RV.

I’ve been using McKee’s 37 products on the coach since we got it three years ago. McKee’s 37 products are an integral part of my detailing toolkit.

I have a few new products from McKee’s 37 Marine and RV line — new to me — and I have been trying them out on the coach. I’ll have a few posts about my experience with these products but today I wanted to highlight one of them that I used last week: McKee’s 37 Marine & RV Final Step Detail Wax.

I am so impressed with this product!

I like to use a detailing wax in between coach washes. It can take a few hours on and off the ladder to apply a detailing wax and buff it out. There is no getting around the fact that a diesel pusher motorcoach has a very large surface area.

With Final Step, the experience can be highly rewarding when you see what this product can do to the finish of your coach.

Here is a shot of the finished front passenger slideout. The middle section is a reflection off the black paint colour of the coach. Incredible!

Another dramatic reflection that shows off the mirror finish.

And another example of the stunning result from using this product.

My coach is three years old and I have taken very good care of the finish which helps a product like McKee’s 37 Final Step to produce such an amazing result. I literally spent an hour or so after I had detailed one side of the coach just admiring the shine.

What an awesome product.

Final Step is very easy to use. The finish should be relatively clean and recently waxed. A detailing wax is not a substitute for washing nor is it a substitute for a full wax. For light cleaning, you can apply a liberal amount of Final Step to the surface with a microfibre cloth and wipe it off without bearing down hard on the paint. Then use a second microfibre cloth to buff out the detailing product and bring out the gloss. That is really all there is to using this product.

Highly recommended to bring out the best of your coach in between washes.

I’ve ordered McKee’s 37 products from Autogeek and Amazon. You can also find them on and
