Fiberglass question

[Joker2]

When I did that layer it was around 70, I applied resin with a plastic spreader, then rolled it out with a resin roller ( hard plastic type ), yes I do sand between coats and also wipe with acetone. I am using 17 oz. Bidirectional cloth backed with 3/4 oz. mat, I guess I just didn't use enough resin and didn't work it in enough in those areas. I just can't stand doing something over again because of my mistake.
