[PSUBS-MAILIST] Silicone

Wed Mar 27 10:00:06 EDT 2019

 Attached is the Psub Paint specification that was presented at the 2011 Psub convention both in Excel and PDF formats.  As Dave Colombo notes, most Sherman Williams paint stores in US are setup for supplying house paint and are unfamiliar with these Sherman Williams  marine products but they can order and as far as I know the account number on the spreadsheet is still valid and can be used for the PSub discount.
I painted the R300 prior to having this paint spec.  I used automotive Imron two part epoxy paint from DuPont for both exterior and interior.  While the paint has held up pretty well, the biggest issue I had was inadequate surface preparation because I could not get interior sand blasted  due to small space and inward facing "T" stiffeners.
The next time I paint a sub hull, I will go with Sherman Williams Psub specification.

 Thanks guysDan H said he used an epoxy paint of some sort but they discontinued it because it caused cancer, I think he said emron or something but I thought the gist of the group here used an epoxy paint but when I mentioned that the other day at our Sherwin-Williams, they were adamant that it shouldn't be used in a semi underwater application, but like Jon says, I don't know any that are. Jon, let me know if you can locate what you were talking about and David, go ahead and send me your contact in Cal.Thanks againJust had another pretty big earthquake but no Lava this time

Rick,
Ditto what David Colombo wrote.  I wish I could remember how the Sherwin Williams Rep steered us back in 2012 (I think it was) but there were certain products that they had which he highly recommended although none of them were in any way associated for underwater application.  I'm going to have to search through archives to see if I can pick up any info.
Absent that, epoxy based paint is used by most that I am aware of.  I know Alec Smyth just used a roller for SNOOPY which provided a matt orange-peel type finish instead of a high gloss sheen, but like he said, it was wicked easy to patch a scratch or scrape that inevitably shows up due to bumping into things, etc.  I am likely going to follow that lead on the K-600.

Thanks IanI know there are a lot of boats out there that are painted so was surprised to not get any feedback. Sherwin-Williams here on the big island said that they don't have anything that will work for an underwater application. Rick
