| Defever Trawler Upgrades - Advice? I just purchased a 1974 Defever Trawler, a 34 foot Passagemaker. It is the only Defever I have ever seen and it was exactly what I was looking for. I couldn't resist buying it. However there are a few things that I would like to change. 1. It has fixed, plexiglass windows that are functional and don't leak but they are a little cloudy and worn. Can they be cleaned/polished or do I need to replace them? Is there a good source for replacements? 2. I would also like to upgrade and have a few windows that open (sliders). Any suggestions? 3. The teak inside the cabin is discolored and dirty, what is the best technique/products to restore the teak? |
