Well, I finished the new console and installed it and now the rest of the boat looks so bad I've decided to repaint the entire boat, inside and then the outside. My question is: How best to prepare the interior of the boat for repainting. How do you get the old paint off? Or what should I do to prepare for the new paint job?
Many thanks already, even though you haven't told me how much work this is going to be!

I have a 65 13' that I am repairing and repainting also! You didn't mention if the boat was painted or gelcoat? This is important. If it is just gelcoated it will be much less work, if it is painted the paint should be removed to the gelcoat, for best results. Here is the process based on the info:

*Strip off hardware etc..
*Wash boat with a slurry mixture of an abrasive cleaner/water (Comet)and scotch-brite pad.
*Wipe boat down with Wax & Grease remover.
*Sand boat with 80-120 grit.
*Do any fairing or repair work required.
*Before priming/painting and any repair work always de-wax & de-grease.
*Prime boat with an Epoxy Primer.
*Scrath sand epxoy, remove dust, tack off, degrease.
*Apply topcoat - spray is best, you can brush and roll.

If boat has paint, follow same process after removing paint. I use 60/80 grit with a d/a sander while being careful of the gelcoat. This is dusty dirty work and not fun.

I use US Paint AWL-GRIP products, they are simply the best for a marine application.
For more detailed information check out US Paint's web site

They have the application guide on their web page and you will have more information than you'll ever need.

Aside from the fine advice Paint Legend gave you there is more information if you expand this topic area to the past year post on refinishing either paint or gel -- Z

Paint Legend.
I believe that my boat is even older than yours, but I haven't been able to locate the forward hull number yet
And I thought it was painted since the interior is BW blue. I don't believe they ever gelcoated in that color. Or did they?
Another concern is getting the deck ready for painting. All those little nubs (non-skid) molded into the deck would seem to present a problem unless I just ignore the fact that they are there and treat the deck as if it were flat.
Thanks for your help . Stan

I recently restored a 1970 16-7 whaler. Interlux is the way to go. Look up their website and call their 800 number for technical assistance. You might want to see my other posts in connection with soda blasting, sanding and surface prep. good luck JimU

Until c.1972 the interior of (some/most) Boston Whaler boats was molded in blue gelcoat.

If the interior is really gellcoat and not paint, wouldn't I be better off if I just cleaned up the gelcoat (assuming it's still in good shape under all the dirt, etc.) instead of painting over it? That would save me solving the problem of dealing with the "nubby" deck. I still have to look for the forward hull number. I hate not knowing how old this little boat is.
And by the way, thanks to all of you for your help and advice.

Gelcoat is preferable to paint (generally) because it is more resistant to scratches. That is because of its thickness. Paint will only be a very thin surface layer; gelcoat will be much thicker. This will allow you to be able to buff out scratches and minor damage, and you can restore the surface to a blemish free appearance.

With paint, you'll likely have to re-coat to cover most scratches and dings.

Reel Remarks,
If you have to regel or paint the non-skid areas, try using a DA sander with red scotch brite pads to scuff the surface. If you need to enhance the effectiveness of the non skid area, apply the gelcoat to the non skid area with a high quality 3/4" nap roller.

You can also dramatically increase the effectiveness of the non-skid surface by mixing interlux non skid compound with your paint. Check it out with any West marine store or on the interlux website.

JC, I would not recommend mineral spirits. It's oil based. Use the manufactureres recommended degreaser. It not worth the risk of spoiling the work involved in surface prep etc to have a coatings (paint failure.)

Thanks Guys. All of you have said something worthwhile. The only one that left me with a question when JimH said that gelcoat is better than paint, and he sounded as if I could apply it to my boat myself!
Did I misread him? If not, what goes into applying gelcoat?

The blue and white BW Gelcoat is available from Spectrum Color in Auburn WA (253)-735-1830. The have D.I.Y. instructions available. You can spray the gelcoat much like paint. After the gelcoat has cured you will need to buff. The advantage of gelcoat was already addressed and is very valid. On the down side gelcoat needs continual maintenance, buffing, waxing, etc... if you are fussy that is. The advantage of a "true" polyurethane (AWL-GRIP or Interspray)is that you only need to wash with water and your done ie spending more time on the water. Once again the earlier reply regarding scratching is the main down fall. Some people add flattening agent for interiors and decks for a satin / semi-gloss finish. This will camoflauge scratchs better and there is less glare on a sunny day. The comment for non-skid is great also, if painting the floor I would recommend the non-skid and once again this will camoflauge scuffing and scrathing. Don't be scared off by paint there are millions of powerboats, sailboats, and motoryachts with paint on them. A good quality paint will last for many years with little maintenance. With paint you usually get what you pay for, get the best and you will not be disatisfied. If you are still undecided call some local marinas or boat repair establishments and see what they recommend as well. I like your stategy of getting all the information and making an educated decision.

Good luck,
