I have been using a product from 3M that is available from marine chandlers, my eagle has severe oxidisation of the gel coat and as a result looked pink instead of the deep red colour it was as new. The first application I made was to the wing top, I applied it by hant to a small area and was delighted to feel the rough dry surface gradually become smooth, and when the cream is completely buffed away there was a patch of smooth deep red, not as per new, but good enough for me to give up on a respray and just polish by hand. I will post some pics to show the look before and after when the bloody rain stops. After a week of bright sunny weather its turned crap again. The product is 3M heavy duty fibreglass restorer wax, can be got for £ 15 from www.mailspeedmarine.com It does work, and I think after I have used this product I will go over it all with the fine grade wax to make it glossier.
i have that stuff and yes i agree it dose work but remember its very expencive for what u get, and the uv has already damaged the gel coat so one hot summer later u will have the same problem, i wod advise taking a layer of damaged gel coat off with a buzz sander 1st other wise ur just polishing the damaged coat, then wet and dry it then use the polish, t cut works just as wel tho
