my dark blue 312 is fading "chalking" mostly aroud the bow end. has anybody had experience how to deal with this?
i tried car polish . looked very good- but only for 3 weeks. would special stuff like from 3M do a better job? or is polishing hopeless and repainting or even "wrapping " the only solution? I would appreciate hearing from anybody who found a solution? thank you!

All coloured gel coats have this issue eventually - called oxidization.

If the hull is fairly new (a few years old), then using an oxidization remover (rubbing compound) first followed by a good wax will restore it for a number of months. Eventually though, after a number of years, even that only lasts a month or two. Doing that on my 2007 looks good for about 1 month then I can start to see some chalking again and after 3 months it's looking sad once again. I recently talked with a fiberglass expert at a boat building/repair company. He said that at this point I should have the whole hull wet sanded starting with around 400 grit and then progressively down to 5000 and then the polish. This will restore it to new. When I have a few thousand dollars laying round I may have it done (I won't have the time to do it myself)

Here's the products I currently use 
Polisher https://www.makita.ca/index2.php?event=tool&id=1905
Oxidization remover https://meguiars.ca/product/marinerv-heavy-duty-oxidation-remover/
wax https://www.westmarine.com/buy/meguiars---56-boat-rv-pure-wax--443226

Note, don't use the one step cleaner/wax. They don't protect that well.

For the removing the oxidization, use a good foam pad specifically for rubbing compounds (they are very firm). Alternatively, you can use a wool pad that is specifically for that purpose. The wool is a bit more aggressive.
