Our JNT-S3 serrated spreader is made out of the same red Celcon plastic as our JNT411B60 and JNT411B90 scrapers, which are Boeing Approved. Celcon is a more chemically resistant plastic when working with solvents. This spreader measures 3” square and 1/16th thickness, with two 1/8" serrated edges, designed to spread sealant.
