Hi Could you possibly give me a first impression regarding the gelcoat on my Sun 2000? It was blown off it trailer a year ago in severe winds and the mast was damaged by the crane driver lifting her back on and had to be replaced. Some superficial gel coat work was also completed. About 4 months after this work I noticed two areas of "crazing" on the hull. At the time I was told boats can develop these but this was an immaculate boat and the more I look at it the more I feel it has been damaged then.

Dear Sir/Madam I need some advice on a boat project, there are two parts that I need a shopping list for and an idea of what to do. Inside of boat: - I need to cover the wood on the inside to waterproof the structure. Outside of the boat: - Again I need to add structure and waterproof the boat. I will be putting a stainless steel plate accross the rear to support the engine that will be hung on the transom. I would estimate the coverage area being 1m2 on each side of the hull.
 

Dear sir/madam I am currently putting together a quote from you for enough fibreglass to cover an area of 325 square metes. the fibreglass would need to be marine safe when fully cured as it is for a Mariculture facility. Basically the fiberglass would need to be totally non toxic when cured and be able to withstand full strength sea water. Regards

Hi, I am refurbishing the wooden deck of my Flying Fifteen. We have stripped all old varnish and rubbed down and moving on to the next step. We are contemplating using West System epoxy. West advice is to use 3 coatings of 105/207 system with 3 coats of two pack polyurethane varnish. All technical info suggests the use of 207 hardener to get clear finish, but if following up with the two pack varnish would this be necessary or could we get away with a cheaper hardener.
 

I read with interest your note on 'spotting' We have a three year old boat that has started to show lots of tiny blue spots in patches around the deck and cockpit. It looks like over spray from a spray gun, but they won't rub out. Is this the same and when you say 'fault' will it get worse and become a problem. At the moment it is unsightly and looks like the top surface is wearing thin in places.
