I will have to face up to the deck on TIH in the near future. The smooth parts will probably be Awlgrip which I will contract out as its too much voodoo for me. The non skid parts I will probably do in KIWIGRIP. I bought two quarts of it some time ago and always planned to do a test run, which the company recommends. The top floor of my cockpit locker proved an ideal opportunity.
I am pleased with the results and ease of application. Search kiwigrip on YouTube for advice.
