InterluxInterProtect 2000E Grey QUART KIT by Interlux

If you are painting a boat, you need this primer to go under your finish paint. It is very stinky, so must be applied somewhere well ventilated, and it is not cheap. But if you want a proper job that will hold up and look good, you need this primer. Read the directions carefully. This is not like house paint that can be applied in almost any weather. It also needs a good roller or brush - don't waste time with the cheap stuff.

I love InterProtect. In addition to using it as a barrier coat it makes a very durable and chemical resistant General purpose primer for metals which is great in a marine environment. Where a fine finish is not required, like parts in an engine room, I don’t even use a topcoat. And it still leaves a decent, gloss free, looking finish.

Used on my cast iron keel. I was able to get 4-5 good coats on entire keel for great primed surface for paint. Dries fast cures less than 48 hours. I will definitely use again

Applies easy, sandable after it dries, its holding up well after two years of mooring in clear freshwater. I suggest this product.

Works great all the time
