Filling nail/screw holes and small imperfections

Postby weasel » Tue Jan 05, 2016 12:47 pm

I am making the tunnel might and it's the first boat I have ever made. What is the best for filling/covering screw holes, nail holes, tiny gaps and imperfections? Do you use the wood filler or a certain epoxy? I see the boats in the photos with this filler covering, but I'm not sure what they use? Have a great day!

I like to use System Three Quick fair. Glen L sells it.

Thanks Roberta,

You sound a lot more experienced than me at this. Are you talking about the Silver Tip System Three Quick Fair (with the bear on the label)? It looks like the yellow stuff in some of the photos in the galleries that is put in corners, edges and over screws, nails etc? How much does a person need a gallon, 3 quarts, 2 quarts? I have the tunnel might, and I assume it matters how many mistakes or small errors in cuts you have too LOL. Thanks a bunch!!

There is also a formula somewhere either in Boatbuilding with Plywood or Boatbuilders Notebook for a fairing compound using whatever epoxy you have combined with some fillers. I can't remember which book or where though.

The 24 oz . kit should be enough. If you think you need more, the 1.5 quart kit is not that much more. You can make a filler using epoxy and micro balloons, but it can be very hard to sand if mixed improperly.

I just used epoxy and micro balloons. Mix the epoxy first and then add 10 times the micro ballon that you think you should. It will be like thick peanut butter. Spread it out with smoother. Let dry. Sands super easy. If you don't put lots of micro balloons in it will be hard to sand. When you think you have enough micro ballon add some more. Then you're just right. Do a small sample first on some scrap wood.

It sounds like the system 3 quick fair is simpler and more consistent. I don't want to sand forever If it gets mixed wrong hmmm. I'm not at all experienced at this quite yet. It doesn't sound like rocket science here, but the more consistent and the easier it is for the first boat would be good. I have the resin and hardener for gluing stuff together, I'm getting the hang of that. How long do you have to work with this 3 fair) stuff before it starts setting up? My shop is about 68 or so here in Minnesota.

Mix small batches until you have a good feel for it. You will have at least 10 minutes.

Are you able to put the water sealer inside the boat over it, and then paint it as well? I am going to fiberglass then paint the exterior so that won't make any difference there. I am going to order his stuff soon here. I'll put it on as I go along building so it's easier to apply. Thanks a bunch

It is fully sealable and paintable like all epoxy products and approved for below the water line.

I am getting the system 3 stuff, thanks for the info. What do you recommend for sealer, then paint on the inside of the (Tunnel Mite) boat, before I close it up?

CPES to seal, epoxy coat, then any good bilge paint. I usually skip paint where UV is not an issue.

What is the CPES sealer? Do you get that at the hardware store, I don't see it on the site? It sounds like some nasty breathing stuff to deal with too.

Then you cover that with the epoxy shield, about how much does it take a few quarts? What is bilge paint? I am new to these terms too hmmmm.

There is a lot of information on the forum. Do some research on painting and finishing. Many of us have posted how we did our boats. System Three has their epoxy book on their website. You will learn much more that way and can see what methods are in line with your own experience and preferences.
