I prefer the low gloss for the interior, but I can't find it anymore. how about an alternative?
Ps. I live in Boston.

Try Lexol Vinylex or 303 Aerospace Protectant. I use Vinylex - it contains UV protectants and gives a satin finish.

What he said... Lots of boating places in and around Boston. Pick one...

I use Vinylex also. Its expensive but seems to do a good job. I have used 303 in the past and liked it as well.

Armorall is crap as it washes away too easy and remains greasy.

ArmorAll also out-gasses badly and you'll find a hazy film on the inside of your windows after a coupla' days. Use the 303 Protectant - (See other thread)

Places that sell canoes and kayaks, as well as quality auto parts stores, are likely to have 303, since these boats are plastic and need the same type of treatment as dash boards and other interior car parts. Try EMS, or the Ski Market.
