Just got an interesting article from Practical Sailor Magazine.
They are running long term tests on sealants and the 3M 4000UV completely failed at five years.
Where it was exposed to sunlight it reverted to its uncurled state. They described it as becoming chewing gum.
They spoke to 3M who admitted this was a problem with 4000UV that was manufactured prior to 2018. They changed the formula in 2018.
