Duratain Sealant Products

[Campin4Ever]

Hello All, I need some help on weather I should get Duratain Sealant Products applied to my new 2016 Jayco Jay Flight SLX (25')? I've been checking out my Trailer before I travel from top to bottom. I got on my creeper & to my surprise the tanks, electrical, and gas hoses were all right there, exposed. So the Duratain Undercarriage Sealant drew my immediate attention. However, I am told by my dealer that I have to pay for 3 of the 4 sealant treatments from Duratain. That is just the way Duratain does it. Cost is $899 tax not included. Duratain is located in Anacortes, WA, and I live in Yakima, WA. So they are a local company which takes some of the sting out of the purchase. Maybe there is another company that does the undercarriage I don't know. Suggestions?
