bilge paint with Barrier Coat?

[GilStump]

Hey guys,

We are making the switch to electric! Motor is out, and now is a good time to make the engine compartment perty. I read here once about using barrier coat instead of bilge paint. Am I remembering correctly? Can't find the thread.

PS: We are making an installation video of the process. Ought to be funny and informative. I'll keep you posted. We would love to answer some questions in the vid. If you have any, send me a private message.

Gil,
I kinda remember that thread as well but can't find it either after a nominal search.
The idea makes a lot of sense to me. It will be a good bit more work doing a barrier coat then using a bilge paint but should outlast any paint if prepped and applied correctly.
Whether you paint or use a barrier coat the prep work will be key to having good results. Removing all residual oils and grease will be very important. A light sanding is likely recommended in either case.
You would need to read ALL the fine print on the barrier coat label and follow their directions. These usually require multiple coats within a certain time frame so each coat actually cures with the coat below it.
If you paint it would not matter when you decide to put another coat over the last as long as the previous coat had dried.
Good luck.

The PO of my boat painted the bilge with the epoxy paint used on the legs of offshore rigs when he repowered. (He had his sources.) It looks good and cleans up easily.
