Bottom Paint--do you see problems here?

These are photos of the bottom of a boat I'm considering for purchase. Seller advertises bottom was stripped and covered with 2 coats of interprotect epoxy followed by 2 coats of interlux micron.

I'm looking at the area (epoxy, I presume) that was exposed after moving the jackstands and wondering if this bottom job was applied properly. Any opinions on whether these photos show any issues?

You might have to zoom in to get a good look.

Boat is out of state. I'm trying to decide whether to go take a look.

What makes you think it was not applied properly? It can be hard to tell from photos. Looks a bit bumpy in one, and in another the "halo" around the barrier coat is a bit strange, but it could just be the light in the photos.

The 'lumpy' is what caught my eye.

Wasn't sure if that was typical of the epoxy coatings or if this would need to be sanded smooth.

Re: Bottom Paint--do you see problems here?

"Lumpy" or what a painter would call "heavy orange peel" is typical of rolled of rolled on Interprotect. A racer would spend a few thousand to have it sanded smooth but the appearance is perfectly normal. Whether it is well or properly applied cannot be determined without a sharp knife and a willing owner

Don't miss out on it over the bottom paint you're going to have to do it again and 18 to 20 months anyway

I was under the impression that the epoxy barrier coat was intended to be longer lived and that it was a much bigger job to re-do.

Yes, the epoxy barrier is much longer lived. It's just the application method that makes it lumpy, rolled on with a large nap roller. It's nothing other than not smooth. And unless you're going to be actively racing at a high level, it's nothing that will slow the boat down.

He was referring to the unpainted bottom paint area (under the pads)not the epoxy.

Re: Bottom Paint--do you see problems here?

It looks like the PO used a long nap roller and did not tip the paint or sand it before putting the bottom paint on.

It is a common practice to alternate colors of the barrier coat so that coverage can be more easily seen. The white "halo" may be the second coat of 2000e. This is especially important if sanding between coats. When you sand through the white and hit gray, you've sanded too much.

If the rest of the boat is worth looking at, then go look at it. If you are going to be obsessive like a racer and want a bottom as smooth as a baby's butt, then you'll have a lot work to do and you'll need a healthy budget for sandpaper or soda blasting.

Re: Bottom Paint--do you see problems here?

I would be much more concerned about the seaworthiness than the bottom paint. You'll want a survey.
