      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

Durepox Paint and Epoxy Automotive Paint

Recommended Posts

Does anyone know the difference between Durepox Epoxy Paint and Epoxy Automotive Paint? To me they seem the same except for the price tag on the Durepox is plenty more........ Its for use on the topsides and under the waterline.

Durepox is apparently used on several AC boats, but they are all dry-sailed!

Hard to get any info out of the manufacturers about the Durepox chemistry, they call it an epoxy urethane, but according to the MSDSs some of their topcoats are in fact acrylics...........

If the boat is wet sailed I believe they advise against durepox.

 

The boat is wet sailed. Durepox is meant to be fine for wet sailed boats as its epoxy. Its polyurethane that is not ok as it will blister.

Durepox is one of the most prefered bottom paints for racing sailboats - Between that and the Sherwin Williams Proline stuff (I forget the material number) .

 

There are no anti fouling properties for Durepox - if you are in an area that promotes marine growth, you need to have to boat's bottom cleaned regularly.

 

Durepox cures to a super hard finish - If you don't knock down the orange peel within 48 hours after application to a 600 grit finish, you are screwed ...

 

The hefty price for Durepox is a function of where it is made , It is a NZL product that is a hazmat ship ...

If you're in the US then use proline, you can get it at sherwin williams stores(not all of them stock it though, Annapolis store did a few years back). It's much cheaper than durepox since it is not coming from New Zealand. When I got it it came in light blue, white, and gray. It is pretty hard to sand also but from what others have said not as hard to sand as durepox. It took a long time to knock down the orange peel.
