My Chevy spark 2014 had as you can see horrible yellow headlights, They've told me this product gives you about a year before having to use it again, so hopefully it lasts. But so far you can see the difference!As for the sealant I recommend putting 2-3 coatings. Overall, the product did the job, we will see durability with time
