I agree completely. Almost wrecked my truck when I saw the "submittal" come across my phone. From: Christiansen, Eric [mailto:echristiansen@halff.com] Sent: Monday, April 18, 2011 05:17 PM To: Eric T. Little Cc: Barnett, Clay Subject: Cleaning of Arches Prior to Painting Eric, Please note that we are NOT recommending the use of Simple Green detergent and wire brushes to clean the arches prior to applying the intermediate coat. Instead, we are recommending the contractor use a commercial blast technique in accordance with the manufacturer's recommendations and our plans. The contractor would only be allowed to use this simple cleaning technique on the arches prior to the application of the top coat. That would also be in accordance with the manufacturer's recommendations and our plans. We have left the submittal open so that it may be revised by Austin. Eric C. Eric S.
