Thru bolt hull to top - advice wanted

Thanks guys. I now have a clearer picture of what I will do. It's a little bit of what each have said - w/ Hermco leading the way !

One question: is it really a concern of the hull-cap joint shifting if I pull all the screws out at once ? Pulling all the screws out at once makes the grinding and glassing that much easier - I can do it all at once w/ nothing in the way.

What sealant is in the joint now ? ( manufact in 1975 ) Should I pull this sealant out anyway and replace with the newer 5200 ?

FYI: I have no leaks in the hull joint at all. I just feel that the SS screw need to get replaced, they have been bleeding rust on the inside liner - and I want to R/R them and add SS bolts... Glassing is a possibility, but 1st I need to see how EZ it will be to get a grinder in that tight spot...

When I did my boat I pulled the cap off the boat to replace all the balsa lamination. When I put it back on the boat it was kind a like putting a plastic top on a Tupperware container it’s a snug fit. I used a crowbar it different places to assist me in this process. I didn’t have any areas that didn’t match up with the original holes of the cap and hull either. But if you did you will find many that would match up and I would put your screws in those first and then work from those locations all around the boat. As for new screws I replaces approx 20% with new ones due to either rust on being a little bent or the top stripping out a little. We all need to remember that stainless doesn’t mean STAIN FREE. As for the sealant 5200 is the way to go as Hermco said.

Did I mention # 10's as above,I don't think I kept an old screw,cleat anything.Went in a Jug & tossed.You shouldn't have a problem removing all the screws.Make sure that You do get them all !I missed eXactly which 20 Ya have SF / MA ? After I put the rubrail on I used the QUICK dry'n sealant under the bottom edge.A lot less runny as this can get Messy !TAPE the hull too. I used besides screws Machine Screws washers & Nylon lock nuts Easy to remove Years later!
