Hello,
I am intersted in hearing more about this product. Once applied can this be sanded?? How much does it cost?? What suppliers have it? What amounts are available? Pints? Quarts? 5 gallon buckets

Any additional information would be very helpful. I have been using foam to creat molds for years and I have always had to coat it with bondo to get a lasting hard surface that would hold up to vacuum forming, etc
Thanks in advance!!
