Why is there white residue on my deck?

[saurav16]

My boat is form 79 and the deck is white. When I walk on it I get a white residue on my sneakers or when I sit on it I get a light white residue. What is going on with the deck and how do I remedy it. I think it is original and has not been painted. Thanks!

Not really, just kidding you.... it's just that the sun has over the years decomposed the gel coat, so it starts to exfoliate...happens a lot to older boats...

Time for some paint or some new protective layer......it's just life..things get old....there is nothing you can do other than cover with new material..it will get worse...

And sometimes new material will not adhere well either...

If its not too bad, you can wax it first(use a three step process). I would try that before you paint. Can't tell without seeing it, hard to tell if you have anything left to wax.

Heres a link to a good thread on it.

There are also good threads on what type of polisher to use for applying a three step process. Not fun by hand. I use a Makita.

Or it could be anthrax.

Saurav-

Stop doing so much coke on the boat...

Chances are very good that it is just the gelcoat chalking up. You need to polish and wax it.

Thanks for your help, I guess woody wax will do the trick. Thanks!

Try jet-washing, with the jet set to a fan pattern.
Works wonders with teak.
