That is a bit much for small projects, nonetheless, I bought several tubes, one at a time, for relatively small bedding projects on my Dovekie.

The reason I wanted to use 5200 was because the hull/deck flanges on my Dovekie had been stuck together with 5200 augmented by a thin band of fibergalss/polyester covering the joint on the interior of the hull. The Builder Edey & Duff, had a very high opinion of the Adhesive-sealant's integrity.

At the time, I was employed in the plumbing manufacturing industry, then subsequently by the aluminum window and door manufacturing industry. Both industries appreciate good-quality Silicone and Urethane caulkking and sealing compounds. I kew that good Urethanes had an expected lifetime much longer than their common use in industry and building trades; almost as long as silicones.

When I phoned 3M one day (I was employed at a location less than twenty five miles from the 3M Headquarters in St Paul) to inquire about obtaining their 5200 in containers samller than 10-oz tubes, the Marketing manager for Urethane Compounds told me that "they were thinking about that, but that 10-oz tubes was it at that point".

When I later began to see small 3-oz tubes of 5200 for sale at Boat-US and listed in the Boat-US catalog, I began to buy it. In fact, I developed a habit of buying a 3-oz tube of white 5200 each time I shopped at a Boat-US store.

I don't EVER want to see 5200 in 3-oz tubes withdrawn from the marketplace due to slow turnover.

I now have some 3M 4200 (also in a 3-oz tube) that I use occasionally. However, I know how to remove hardwre bedded in 5200 quite easily, so the common admonition to "never bed anything in 5200 that you might want to remove later" rather laughable.

BTW, my present Edey & Duff Shearwater has the same sort of hull/deck joint that the Dovekie had; 5200 squished between the flanges, with a thin fiberglass/polyester cosmetic band around the interior; no mechanical fasteners of any kind. I've owned first the Dovekie, then the Shearwater for a total of 27 years.
