Before all the negitive and counter productive comments come in, I know... I know.

Here's the deal I have more customers then I'd like who just won't stop using tunnel washes BUT want a good "wax" to protect from the harsh sun here in the desert. I normally recommend they use a local touchless wash but not sure how harsh those chemicals are so I've come to my friends, my family, all of you here on AGO.

I know if a sealant should last 6 months with proper washes a tunnel or touchless will likely reduce that by half

With all that said which sealants would you think I can offer to these customers to keep the paint protected from the sun but will last the longest through the torturous tunnel and touchless washes. Feel free to list 2, one for each method if needed.
