I have used Rubber seal in the past and it was good for the price. I have lately been using Performance Series clear with great results. unfortunately I just had a catastrophic failure on one of my best looking jobs. Luckily it was my own, but the supplier said theres no warranty for the paint. When he originally sold me on the clear he said any failure would be warrantied. I have now switched back to PPG. the only time I don't use PPG is if the customer is willing to understand that I can't guarantee the paint job.
