Mr Mac:
Thanks for your post including the pictures. As another Cherubini Hunter owner (1980 build), your post/pictures prompts the following observations which were successful for me:
- Upon my purchase of my boat, the non-skid sections on the side deck, the cabin top and the cockpit seats were much like in your pic's. Stained, but in very good mechanical shape underneath the grime. Using a an electric 1400 psi type pressure washer on the "fan" setting and the gun end not to close, I was able to clean the non-skid very well and get off the surface oxidation without damaging further. Underneath, all the original stippling relief was still ok - almost new looking. But I was concerned that maybe this wasn't the case for long in the continued UV exposure. So think about re-coating the non-skid before it begins to degrade. I used Interlux 2-part Perfection mixed with their non-skid granular additive and mixed with their flattening agent to reduce the gloss. I did this five years ago. And the non-skid today still looks virtually brand new. Because a perfect application finish isn't required on non-skid, and I knew that the area was never waxed, all I did was mask the areas and paint on with a brush. Just took a morning. Because the non-skid section has lots of surface porosity, no pre-primer is necessary. I suggest that you choose a color that matches your existing non-skid, or at least is close. Two part Perfection will last many years longer than one-part non-skid finishes.
- Your port frames still look OK. But again, UV is bound to take a toll soon. I painted mine with Rust-Oleum's hammer finish paint to protect. Easy to apply and lasts a couple of years. Refinishing with a second coat after a few years is just matter of just aggressively wiping off the surface oxidation with a terry-cloth rag and repainting. Attached are a couple of pictures of my boat after painting the non-skid the port frames.
- If your exterior smooth gel-coat on the cabin top and in the cockpit is still ok (mine wasn't and needed repainting), wax it soon to protect. Resist getting wax on the non-skid if you do think you might ever want to paint the non-skid sections.
- Going inside: Best I could tell from my boat, Hunter's original treatment of the teak was simply teak oil. I found that a product called "Zep Industrial Purple", a very strong water based cleaner/degreaser available at Home Depot, removed the years of grime from the surface, but didn't remove the underlying stain or damage the teak. Here is a link:

And wipe off several times with another sponge constantly refreshed with clean water. Be sure to wear protective gloves as the stuff will cause detergent burns. And be careful about splashing/dripping the "purple" on anything that you don't want to clean. After, I just applied MinWax "wipe-on" polyurethane to protect and give the teak a satin sheen. Looks great to my eye compared to actually varnishing everything ... and a lot easier. Industrial Purple will also do a great job I think on the interior mold. And in your engine room. I can't tell what "wall fabric" lines your v-berth. Mine was a vinyl wall paper that looked like straw weave. It was filthy and wouldn't clean with normal cleaners. Industrial Purple did cut through and the vinyl is now almost new looking again. Much easier than removing and re-applying new covering. About Industrial Purple: Your discretion about what to do with the drainage waste ...
Hope the recount of my experience gives you some ideas.
