I 've been using a fiberglass product that I had been buying from a large chain store. I bought my first gallon of Evercoat Fiberglass Filler and I quickliy notice the difference. Evercoat is easier to apply and sand. I used about half of the gallon and then bought two more. I have a lot of fiberglass work to do on my Batmobile project car and Evercoat is the only product I'm going to use.
Great stuff!
Thanks.
