Washing full body paint

I used brushes for years. When I bought my Newmar, I went with what they recommended and I'm using the lambs wool. I'm also trying it on my 3M mask. I believe that over the years, using the brush on the 3M mask, caused micro scratches. I only use a lambs wool mitt on my 3M mask. It will obviously take years to see if this was the way to go.

For what's it's worth, the lambs wool works just as well on the paint as the brush and is just as easy to use. The only place it doesn't work as well is when cleaning the windshield.

Boar hair brushes are expensive but they won't scratch and they last forever

Using a wallyfworld brush will damage the clear coat. People "THINK" there are no negative effects, but there is. Micro scratching is cumulative and then a few years down the road you wonder why your paint looks so dull. That's because you've been adding scratches each time you wash it incorrectly or use some inferior washing product.

IF you want to use a brush, the only brush to use is a Montanna Boar hair brush. It's expensive at $90 but it will last you a lifetime with very minimal harm to the clear coat.

Employ the 2 bucket wash method and the boar hair brush and you'll be doing minimal damage to your clear coat. FYI all washing does some damage, you're just trying to minimize before the paint needs to be corrected. Anytime you rub something on the paint to wash it, you're causing damage.

Just remember people think they are doing no damage to there clear coat, but they just don't know what to look for. Just take a flash light and point it at the paint at an angle, that's when the damage becomes evident. We've all seen those coaches that when the sun hits it at an angle the swirl marks are everywhere.

One washing from the dealer and I can see the damage he put in my paint, that's after I told him not to wash it.

I must say for vehicles that are this expensive it surprises me that a good 98% of the recommendations on caring for the paint are just flat out wrong and damaging. I've been detailing cars for 40 years, which includes many show cars and I would never treat the most expensive vehicle I've owned any different for the sake of speed.

The first thing you want to do is get a quality wax or sealant on the paint. Use a quality PH balance car wash shampoo.

Stay away from that Mary poppins waterless wash junk. It's a gimmick and nearly always used improperly.

Just know that there can be issues with micro fibers. There are many grades of micro fiber and some micro fiber really clings to debris. You don't want to get a cheap micro fiber that holds onto a piece of dirt and you drag it all over the paint.

A good lambswool pad or the boar hair brush would be the best. I use the boar hair brush on an extendable paint pole and then use a good quality lambswool for the parts I can reach. This is after I've rinsed, sprayed with a foam cannon, rinsed again, foam cannon again, then the brush. Flushing off as much of the debris is THE MOST IMPORTANT PART, followed by the 2nd most important part which is the 2 bucket method (using one bucket to rinse off debris washing implement then another bucket for dipping in suds).

Listen to newmar. Mine has been resided because of side wall checking and that info was restated to me as the original clear coat had fine brush scratches in it. Saw many the same way at nappanee. If you find a brush that does not scratch fine, but I took their advice and no scratches.

I have used the brush and still do but a pad on an extension is preferred.
I rinse the brush and pad between use and dipping back, in the bucket of suds.
The brush mostly on windows and windshield.
Rinse it thoroughly before even starting. I use to decry pressure washers but on moderate and away from window seals and doors it will dislodge almost all grit and dust. it or a high pressure water hose is a must around lower edge and wheels. Newmar is right. I polished my coach once, never again, to get rid of spider webbing and worse. I will have to do the rear though.

She does both Tiffin and Newmar cleaning sections in the owners manual. Really nice lady on the phone too.
Now having said that I used the soft brush on the Ram and 5er and they still looked great.
But for the money these things cost I wasn't going to chance it!

Ditto, use a soft car wash brush I bought from Wally World, no negative effects.
