sealant

My new detailer is proposing to use Jetseal sealant as a finish product, instead of traditional wax. I've used Reject sealant last year and was not happy. Does anyone have experience with Jetseal?

I removed all the hardware and all the caulk from every seam on my 310 Sundancer before I refurbished it. I now need to recaulk everything, inside the cockpit and out including the rub rail top and bottom. I will be remounting stainless hardware as well. What white caulk and sealant do you all...
