I used polyglo on the deck of a Hunter25.5 that I had and it made things look fantastic. It did wonders to the 20 year old gelcoat. It is easy to apply and gave the boat that wet look. It last for many months and if you apply more before the sun eats into it (about 6 monts for me) it stays looking good. Another benefit is that you can polyglo the nonskid. Sealing up the gelcoat helps it repel dirt. Here is my delima. I have been working on the deck of my 85 28.5. I have fixed many dings and even had gelcoat sprayed on a few spots. The deck is looking pretty good and now i need to shine it up. I thought about using a wax but what holds me back is that it does not seem to last very long and you can't wax the nonskid. When it is just left unsealed it becomes a magnet for dirt and mildew. What are other people having success with and do you treat the nonskid? By the way, the polyglo does make the nonskid slippery when wet but I solved that by lightly hitting it with 600 grit sand paper. I have had real success with polyglow on ther hull. It really looks great and last longer because the direct sun does not hit the sides.Jeff
