1973 Chrysler Fin & Fun Rebuild

Re: 1973 Chrysler Fin & Fun Rebuild

You asked about bottom paint. I used Interlux VC Performance Epoxy bottom paint. It is a 2-part paint that's rock hard when cured. The one gallon kit actually comes with 2 gallons...One gallon base and one gallon hardener. I put four coats on my boat and still have about half of a gallon left.

did you have to spray it on?

Re: 1973 Chrysler Fin & Fun Rebuild

I did spray it. It sprays easily with a paint gun. I think it can be rolled or brushed on as well.

Re: 1973 Chrysler Fin & Fun Rebuild

Just so you'll know the Interlux VC Performance Epoxy is somewhere between $150 and $200 bucks per gallon. Very good stuff but pricey.

I paid $135 for 2 gallons @ Wholesale Marine. It was on sale then, but it's back to $153.90 for the 2 gallons. Free shipping on it, too. They may run another sale.

Sooo..Did you get 2 gallons of Paint and 2 Gallons of Hardener or.. 1 Gallon of Paint and 1 Gallon of Hardener which yields 2 gals of Product. I'm confused. :confusion:

Plan to get everything out of the hull this week, of course after taking many measurements.

Re: 1973 Chrysler Fin & Fun Rebuild

Last night a me and a buddy went we dumpster diving to get some pink 2 inch foam Foamular F-150 2 in. x 48 in. x 8 ft. Scored Squared Edge Foam-45W at The Home Depot
We ended up with 2 truckloads of chunks and strips of foam. We definitely got enough foam to fill under the floor.

Any thoughts?


Also, we got all of the old floor out along with all of the foam. It took about 3 hours. (Will upload pics tonight) it was backbreaking but at least it's done and now onto grinding

Re: 1973 Chrysler Fin & Fun Rebuild

I think I need a Tetanus shot after looking at those pics!

That's some nice algae you got growing in that hull, I'd spray it with bleach and then pressure wash it.

As for the foam, the pink sheet foam is more of an aluminum boat foam... but you can still use it in that f'glass boat, but you'll need to use the expanding urethane foam with it. You can use the pink foam to lessen the amount of expanding you'll need by laying the pink foam in first and pouring the expanding foam on top of it. The expanding foam will fill all the voids below deck and support your deck and hull, f'glass boats need this support.

Now for the fun stuff! :faint2:
Don't forget the Tyvek suit and respirator!

Re: 1973 Chrysler Fin & Fun Rebuild

Painting "Flake" is, IMHO, not for a amateur beginner painter especially without a booth. I would stick to either trying to restore the Gelcoat that's there already, or painting with a good two part paint. If you want to paint it "On the Cheap" but still have a durable finish check out the last link in my signature below.

Wood, how do you go about restoring the Gelcoat? I am having sort of the same issue, I would like to paint my hull and and cap also. (Mainly the cap).

The current gelcoat on the cap is in pretty good condition except for certain parts where the seats were that are stained black and I can't seem to get it off. Maybe you can shed some light on my little problem.

Haha yes a tetanus shot would be good

If you are referring to the greenish looking stuff on the hull about midway up the boat, that is actually the glue from the old carpet that was in it. However, a good cleaning would be a very good thing.

The foam is the thing I am most worried about at this point. I was thinking about trying to PL glue all of the pieces together into 1 huge block 22 inches wide by 12 foot then use a rasp to shave it down to fit perfectly in the hole that needs to be filled. Then I was thinking about wrapping the fitted foam block with plastic so it is completely sealed and no water can enter and saturate the foam. Once the foam is sealed, PL glue it to the hull. Then since it will be a perfect fit. PL glue the underside of the deck to the foam block as well

I am thinking this would add a lot of structure to the hull/ floor

Re: 1973 Chrysler Fin & Fun Rebuild

Rotten boats are the best! I loved mine when it was that way. I love it even more now that it's not. By the way, I got away with doing my whole redecking and transom without any jig fixtures, but it's not recommended. I had to re drill about 8 holes in one area of the hull for the cap to hull attach rivet line, but that was the only grief. And not much grief at that. I pulled my cap up to the rafters in the garage where it stayed all last winter. We pulled about 12 Pacific Halibut and maybe 25 or 30 good sized ocean King Salmon with it after all that. I'm going to install a new windshield this winter. By the way, it's Chrysler all the way for me in the Pacific. 75 bucks for my 75 horse unit and I've cranked off 550 hours over 4 ocean seasons with it.

That looks like a great boat. Looking forward to your progress!

Thanks Sea Stomper!

I plan to support my hull before I do anything else on the boat. I am extremely concerned about my floor being level.

Any thoughts on my foam idea?

Floatation foam in a fiberglass boat serves multiple purposes. It not only keep the boat afloat in case of an emergency, it also supports the hull and deck and unifies the structure by filling all voids and creating a solid core... and that's one of the problems with using sheet foam alone in a f'glass boat. Sheet foam will leave a lot of voids because it doesn't conform to the exact shape of the hull. This will leave a lot of the hull unsupported and is likely to cause stress cracks in the hull, especially in older boats like yours. This is why the smaller (under 20') f'glass boats are manufactured with solid expanding foam below the deck. It would be quite a bit cheaper for the manufacturers to use the sheet foam for floatation, but the boats would hold up over time.

I touched on this subject back in post #30.

You can use sheet foam and expanding urethane combined to give your hull the support it needs and to greatly reduce the cost of the expanding urethane foam. You can "sandwich" the sheet foam in layers between layers of expanding foam. This can reduce the cost of the expanding foam by about 75%.

As for wrapping the foam in plastic, it's not recommended. This will break the adhesive bond between the expanding foam and the hull. It'll also trap any water that gets between the plastic and the foam.

I know you're probably thinking "I don't want to use expanding foam because it's just going to suck up a bunch of water like that junk I just dug out of my boat", this isn't true. It takes a long time for urethane foam to become waterlogged and it has to have constant exposure to water for that to happen.

A quote from the USComposites site:

2 LB Density Urethane Foam
(U.S. Coast Guard Compliant Marine Foam)
Common Applications: Our 2LB density marine foam is recommended for void filling in nonstructural applications. This product can be poured underneath decks and inside cavities where a lightweight flotation foam is needed to provide buoyancy. This foam has been tested in accordance with U.S. Coast Guard Regulation # 33 CFR 183.114 . This foam is approximately 95-98% closed cell which resists absorbing water, however continuous water submersion can eventually lead to loss of buoyancy over a period of years.

If you take care of your boat when you're finished restoring it and protect all of your hard work by keeping your boat covered when it's not in use your foam will stay bone dry... and your boat will stay looking new for many years.

Your boat was severely neglected before you bought it and that's why it's in the condition it's in today. When the interior of a boat suffers constant exposure to the elements... it ends up like yours did.

Ok! Thank you very much I really appreciate the feedback!

How would you suggest me using my sheet foam with the expanding foam ... I am not sure what the , most efficient way would be to combine them

I actually just ordered some foam for my boat, for some sections I am planning on throwing in some small chunks of the sheet foam to take up some space. How I was thinking I would do it is basically calculated the volume of the section of the boat i am filling up, minus the volume of the sheet foam that I will use, then I would mix up the expanding foam and pour in half so that the foam can adhere to the hull then play my pink foam chunks on top and finally top off with the other half of the expanding foam. This must be done quick however since the foam begins expanding quickly. Hopefully if your volume calculations are correct the foam will expand and fill up your area without overflowing or pushing out the sheet foam.

I am roughly where you are in your restoration, if you have any questions I can always try and help, but not as much as some of the other guys on here. Good Luck! I'll be following along.
