The on-going rebuild of the 1977 Silverton is continuing and this morning Gel-Coat Jim began preparing some of the nicks in the original gel coat surface for recoating. With a small grinder he removed all of the loose gel-coat around each of the nicks in the surface. Its important to remember here that a small nick will often require grinding back a significantly larger area around the preimeter of the nick. The photos below show the three areas on the boat’s hull that are going to be recoated.

After grinding as shown, you need to be extremely careful not to get any wax or other contaminates onto the ground down surface. It’s a good idea to wash the area with acetone to clean out the area and remove any loose grinding particles. The remaining surface is comparatively porous so if the gel coating is not going to be done immediately its also a good idea to cover the area to keep it clean.

Hopefully Jim will be applying the gel-coat tomorrow morning so we can get a look at that part of the process. I’ll be checking in before I fly to Kansas City, MO in late morning.

You may be wondering why I’ll be in Kansas City. Not much water out there. Well, I’ll be acting as a judge at the Skills USA national championship in the Marine Service Technology area. This is a trip I make every year and the contest is really a chance to get a first hand look at the best and the brightest students from marine tech programs from around the US. The future of boat repair is competing head to head to see who comes out the winner in a challenging contest that is comprised of both written and hands-on skills related to boat repair. I’ll be reporting live from the Kansas City Convention Center beginning on Wednesday.
