Just get this and don't waste time and money for cheap clear coats. That's what I did many times and now after trying this I see that I wasn't that bad at spraying - just had a wrong product.
It covers great and will even even-out the base coat a bit. You can wet sand and polish it after 24 hours, but if you can wait 48 even better...
For real, I don't have a bad thing to say about this product. The fact that it will cure once activated might be an issue (but also that's why it's so good), but I put it in the freezer as some recommended, we'll see if it's still good if I need it again.
My job took two days (wheel wells, 1 side per day) and I kept it in the fridge between the days - worked well. After all was done it went to the freezer.
