They would install a flow through plug, pressure clean the surfaces, apply Quadex Hyperform, to bring the surface to the proper contour, and then apply the Raven Expoxy coating. It normally takes about 3 hours. (See attached file: Raven405TDS.pdf)(See attached file: hyperform.pdf) Please advise if this may meet with your approval so we can schedule the work to be done as soon as possible.
