Waxing/buffing a possibly thin 1973 SeaCraft Hull
 
Hi, I have a 1973 20 Ft SeaCraft potter built and I was looking for an answer to a question I have about buffing the side and I ended up on this site. I am not the first owner of this boat and she definitely was not keep in premium condition for most of her life. There hadn't been any real restoration to the boat until this year when we got the transom rebuilt, since then I have started to keep her in much better condition, I have been hesitant to take a buffing wheel too the side of the boat to get a nice wax because I'm afraid that the hull is so old I might just poke right though the gel coat; what do you think the odds of that realistically happening, my father also believes that if I take the carpet up from underneath the gunnels on the bow that the glue holding that down could also be holding the hull together because it hasn't been touched in 50 years. I really hope he is wrong because I believe it would look much nicer without the carpet - I tried a small area and it came out very nice. I was thinking there might be a product that I could apply weekly or something that would slowly thicken the gelcoat or built up a thick coat of wax so I could start buffing it again. Tell me he's crazy and it would be fine, if not and he is right is there any such compound that would thicken the gel coat or should I leave the carpet on, or at least how thick should the hull on the bow be?

Thanks
- Sam

Unless the previous owner screwed that hull up really bad, not likely. That is one of the most desirable 20 footers ever built

Should I still be able to run a buffer though?

Thats a fiberglass boat back when they made them right. I can’t imagine you are going through it with a buffer. If the carpet is holding your boat together, you have no business taking it to water. Things to look out for are broken stringers and rotted transom. Assuming you have an outboard you can grab in and shake. Transom shouldn’t move at all. If it does you should get it fixed.

Aloha brother.

I have a 72 seafari 25. My hull gelcoat was sanded by the PO. If that hadnít of happened it would easily have been ok.
my decks were painted this ugly brown color. After I sanded that off my gelcoat was in perfect shape there. I would check your tabbing, bulkheads, etc.

dive on in. The waters fine. Maybe post some pics?

The boat is made of fiberglass, then they put gelcoat on top. You might buff through the gelcoat, but not the fiberglass. If the hull was that thin it would have buckled the first time you took it out. Try buffing a small spot and see how it turns out.
Rip the carpet out. Don't listen to your father. He clearly knows nothing about boats.

This is the orginal gel on my 77 SeaCraft Sceptre after spending a day with wetsanding, buffing, polishing and waxing. Not perfect by any means, but she cleaned up nice for an old rig.

Gelcoats are usually around 20/1000 of an inch, .02". Just a protective and decorative layer. The fiberglass can be 1/4 to 1 inch thick or more, depending on what boat and what part of the hull. Buffers can burn the gelcoat, and gelcoat can wear down and through over the years. Buffing through a gelcoat that isn't already worn thin is unlikely, and buffing through any significant amount of fiberglass is near impossible. There are a lot of videos online that can teach you how to buff without burning or excessively wearing your gelcoat, best you watch those before doing it yourself. Maybe ask someone experienced to let you help them buff a boat while they teach you.

As far as the carpet glue, no, it is not a structural part of your boat, you can remove the carpet and glue without compromising the strength of your hull. If there is structural weakness in your hull, carpet glue is not going to make a difference.

When you get a few more posts in, you can post up some pictures, guys on this forum can give you a lot of good guidance from a few pictures.

I just went to our local boat supple store, its definitely no west marine but they did have some 3m Restore and Wax, it was $40 bucks and i'll get it but I don't want it to be a wast of money - Has anyone with a SeaCraft tried this? Also the classic old boat guy who ran the store said I should stay away from buffers on a 50 year old boat - any thoughts?

See my post and pic above on a 50 year old SeaCraft. Used a dewalt 8" high speed buffer.

Buffer with a wool pad, a light cut compound like Aqua Buff 2000 (not the 1000) with water spray mist per instructions. Then Collinite 920 and a coat of the 925 wax. I've buff my 42 year old SeaCraft about every three years and wax every year. Again it's 42, not a new SeaVee with pretty gel coat!!

Yours is probably better, don! Happy belated birthday.
