Painting Hull

Hi everyone, I recently purchased a Victoria 18. Before I get her out on the water, I would like to paint the hull. My father used to be in auto body, so I'll have him spray it, but I will be doing all the prep work. The boat will be sailed in freshwater and I'm thinking of going with Alexseal paint, any opinions or suggestions on freshwater paint?

Should I sand the gel coat completely off, or just sand enough for a good painting surface?

How much paint will be needed? I plan to do red below the waterline and blue on the topsides.

Clear coat over paint?

Any tips or tricks I should remember?

I searched the forum for a bit, but didn't find these questions.

Thanks.

Re: Painting Hull

No need to remove the gelcoat, unless you've had some sort of catastrophic failure. You'll need to fix the scrapes and gouges using epoxy products like those available from West or Mas, then sand...keeping it FAIR...and then paint.

I'm not familiar with Alexseal, but would strongly advise you to go with a 2-part coating like Awlgrip for your topsides. Clear coat's not needed. A two part will have all the gloss and durability you need or can get.

MUCH has been written about preparing and painting topsides with 2-part paints. Between Google and youtube you'll get what you need. West System epoxy also has plenty of free info online.

Below the waterline, VC17 is ideal for freshwater. Easy application and low buildup. If you want to add blister protection, coat the hull with something like Interlux's barrier coat, and apply the VC17 over it.

The project you're planning is a reasonable undertaking. On the one hand, pretty simple taken step by step, but on the other hand, too complex to fully explain here.

Avail yourself of the available info, take reasonable care, and you Victoria will be beautiful.

Re: Painting Hull

I re-read your posting and saw that you will be spraying. Lucky you. Awlgrip should NEVER be sprayed by an amateur (use a roller), but a pro can do it.

A little bit of homework will tell you which 2-parts are most suitable for spraying. Imron comes to mind.

If you repair the topside scrapes and gouges to auto body standards and spray two part on it, you will need protective goggles to view the boat in direct sunlight! You can expect it to look as good..OR BETTER...than new.

Re: Painting Hull

a Cheaper alternative is a one part like Brightsides (which is really a polyurethane)... it can be sprayed, but you must use their thinner (or approximate their thinner using a formula found easily on the internet

I used 4 quarts of paint on my 25 footer... 2 is probably all you'll need for your Victoria if you prime it correctly... Did I mention you should prime it? I did not for mine, and therefore had more coats than I would have needed otherwise.

A HVLP sprayer will work with most of these thinned following instructions by the manufacturer.

Alexseal is also a 2-part LP paint, just like Awlgrip. In fact, it was invented by the same guy who invented Awlgrip, after his non-compete ran out from selling to AkzoNobel. The new formula is designed to be just as tough, but more easily repairable. Ironically, some of the ingredients in his original Awlgrip formula are not longer legal, so Awlgrip isn't even Awlgrip anymore.

He even makes Alexseal in the original Awlgrip factory, I believe.

I used it for our repaint a few years back. Very satisfied so far.

Re: Painting Hull

It is possible for an amateur to get a decent result spraying awlgrip or any other 2part paint. Biggest issue is finding and using the appropriate respirators and work in well ventilated conditions. Read and follow directions to the letter and if possible have a 'mixing crew' available to prepare batches as you spray.

You may not get pro results but you'll save a bundle. A reasonable motto might be ' far from good but good from afar'

FWIW we did a 40 footer ourselves some years back in awlgrip.. Turned out OK.

Re: Painting Hull

If your Dad can spray it in the shop then Imron is the way to go as it will behave in a way he expects

Awlgrip and Perfection require a completely different spray technique that will give a person used to "normal paint " FITS

Re: Painting Hull

Yep, I'm jealous, because I have no patience, and can't spray to save my life. I bought a cheap HVLP sprayer, and my result was terrible (bad thinner I suspect - couldn't possibly have been me).. but I CAN say that roll and tip isn't bad either..

10 foot rule... if it looks good at 10 feet... YOU RULE!
Here, entertain yourself at my expense...
