I spent $ 800 for a patch job on my RV. Dishonest and pushy describes my experience. I can say that he stopped my leak but it was a very sloppy job, coating on all of my ac shrouds. I got what I paid for but wish I had spent the money to have the job done right. No way I could ever trade in or sell my rv the way it is, will be looking for someone to pull up his work and do it right.
