Hi everyone, I've had a Norman 20 since the summer and up until now i have not had time to do the restoration work.
The Hull although sound and watertight is in a sorry state with chips and gashes right through the gelcoat in several places. the wood panels on the side of the hull are completely rotten too.
My questions are:
1) Is it difficult to replace the gelcoat and if so what is the best method? 2) Can anyone recommend the best type of orbital sander to use? 3) i'll try post some pics tonight 4) any tips or advice welcome
"replacing" Gel coat - Very hard... Filling deep scratches... Plastic Padding Gelcoat filler.
Best sander Dual Action or commonly known as DA
Sand flush and progressively work to finer grades..... ending up with 1000 wet and dry..... wet. The polish using G3 - G6 - G10 Farecla cutting compounds.... finish with a good wax.
Upload your pics to a hosting site like this: http://tinypic.com/ (Choose the 640x480 resize option) Then copy the forum code that starts with IMG in square brackets and post it here. Or just upload them and post a link.
There is a box on the left hand side of tinypic page that says "IMG Code for Forums & Message Boards" Copy the contents of the box and paste here and it should display.
The wooden strips along the side of the boat are rotten so I think I'll remove and fill the screw holes and hot replace them.
The rubber protector that goes around the top of the deck seems OK but it looks as if there has been some rope glued into it for added protection
My main concern is the large repair patch on the hull at the front. I don't think it's letting in water but will ensure it is covered well with primer, undercoat and paint when it comes down to it.
There seems to be large areas on the hull which are like orange peel. After doing some research I beleive that may be osmosis although not sure. I'll post the pics and be grateful of any feedback and comments. Cheers
Nope... thats what the waterline looks like on any 30+ year old boat. Mask up with tape and paint a thick coat of anti foul or better still boot top paint. Job done. Walk away and worry not!!!
Osmosis is larger than that.... starting about the size of a 5p and slowly swelling to the size of dinner plates!! Usually forming randomly and way less frequently than your waterline, and usually underwater.

It's not much of an issue on smaller and low value boats as the cost to professionally treat it far outweighs the value of the boat. A sensible way to treat it is to grind out the blister in the autumn, dry out over winter and fill in the spring.
I was in a panic there I could see the pound signs clocking up. I'm going to start the sanding down tonight and spend all weekend doing the prep for painting. I'm still looking at what paint, primer, antifoul to get. I want to do a good job but also want to get on the water asap. I'll do some online shopping tonight and get what I can.
