Review on 🏗️ EternaBond 2.5 lb 2-1/2" Wide Curved-End Ball Bearing Steel Roller - EB-R125R: Durable, Heavy-Duty Roller with Enhanced Control for Optimal Performance on Various Roof Surfaces by Alan Miller

This tool is essential for the correct application of Eternabond and is a bit expensive. There are similar tools out there but nothing quite like it and it worked great installing Eternabond on the roof seams of my fifth wheel. The crucial point is the rounded edge, which cannot damage the outer surface of the Eternabond. The reason I only gave it 3 stars besides the cost is that it rusted within a week or two and never got wet. Eternabond worked great. Last night there was a 80 km/h wind and heavy rain, not a drop indoors.
