Staff at Fogh are excellent, and I can't say enough good things about the Epifanes exterior matte product. I needed to refinish my very large solid wood front door, and wasted days trying to get Helmsman oil-based matte finish spar to go on without streaking, failing to lever, and showing significant variations in sheen. I followed all advice from Sherwin Williams and nothing worked. Out of total frustration, I read about Epifanes, talked to the staff at Fogh, and decided to try it. Thank goodness I did. It went on perfectly with no streaks, a consistent matte sheen, and it keeps a workable wet edge for a reasonable time to ensure coverage. I only wished that I started the whole project with Epifanes, but at least I've learn my lesson, and I will only use Epifanes - it is truly the best!
