This product is a massive headache used on my car headlights did not get the headlight clear after 4 hours using the rubbing compound and the clear coat did not dry . took the headlights out of my car before useing as it clearly states you cannot apply the sealer polish in direct sunlight. I am sure the manufacturer or suplier would say it was the end user , I was taught french polishing as a lad .You should not buy this product. All the product was taken off whith car body rubbing compound and resealed with carnauba wax
