the sealent itself is decent stuff. dealership i used to be a manager at uses it. the interior part of it is just scotchgaurd. I've applied it to a few cars plus mine, one of them about 8 months now.. those cars still bead like they have a day old wax job. The bugs come off with ease with no apc. I give it a A+
The trick is once you apply it, don't use any harsh cleaners on the applied areas. Just use car shampoo and water. Once you open the seal on the bottle, its only good for 3 days tops. One bottle is enough to do a large suv. Use it on everything. paint,windows,plastic moldings,wheels.
After you apply it try to keep it dry for at least 24 hours.
Here attatched is a photo of my buddies ride that i've applied it too. Say what you want but the price you have to pay at the dealership is worth it for the sealent at least.
