Hull Bottom Panels | More Primer & First Gloss

I haven't posted for a while because there simply hasn't been anything of great visual interest to report.

I have spent the last few weeks learning how to paint a boat, or more specifically how to use marine paints. It doesn't behave anything like household paint, and advice on what to do with it varies widely.

In the previous post I had sanded the bottom panels to a really smooth P120 finish and was ready to repaint them with primer.

More primer arrived a few days later and I prepared to thin it, as recommended on the 'how to apply primer' video tutorials which I had researched.

So I read the instructions on the tin before proceeding, and was dismayed to read "Do Not Thin".

Hmmm. I called the paint manufacturer and asked them about thinning the primer. They said that would be OK for spraying, but 'not recommended' for brush and roller application. In other words, don't do it.

The new paint certainly flowed better than what I had been using, so I showed good faith and applied three coats over several days by careful rolling and tipping.

This is what it looked like.

It didn't look too bad so I went ahead with the first coat of gloss.

Again, this is what it looked like.

I wasn't convinced that it was good enough, so left it until the following day.
