So last night was productive now have all the paints and stuff i need from Boat Paints in Freo , Gary was super helpful and gave me great advice he knows the boat well... got colour matches paint for touchups and a 2 in one primer and topcoat that will need 2 coats and job done... a very light grey in colour... Gary had used it on his amazing metre boat reno...
So went to 60 grit on the random orbital sander works great also discovered a lot of the flakey stuff comes off with a scraper ... also found the best fibre glass matting super strong stitched stuff this will be super strong for all me repairs just what i needed ... so all glassing with be with 650 chopstrand then a layer of super matt and then 2 more of chopstrand which can all be done in the one pour which is cool...
touch up paints means i can now plug all the swiss cheeze holes and get ready for bedding down hardware....
Gary advised that 1/4 inch ply would be fine for backing plates so i might do that to save time and money....
so a funny thing happened there was all this discoloration that looked a lot like it was half painted... turns out just grime mould whatever it was all came off with cloudy ammonia worked so well... i had previously tried sanding this stuff off with no joy... cloudy just stripped it off like it wasnt there, saves me a lot of sanding so will just need a light sand for mechanical bonding and we are getting close !!!

Thats the super matt in the second pic bought 3 metres so chunky!!!!!!!
