Here are the exterior pics after weeks of working on that tar. And yes.....paint stripping gun, plastic putty knife, rubber gloves, and Jasco Adhesive Remover. I spent about 100 man hours and $200 on Adhesive remover, blue shop towels, and gloves. Every window was covered in tar, all the roof seams, rivets, and roof openings. My boyfriend took me out for beers and burgers to celebrate! The scaffold and metal studs are things we use in my construction company. Next....take off all the windows and drip seals to clean and re-seal.
