Once the peel ply was stripped and the epoxy was partially cured, it was time to fair some more. The use of peel ply made a generally smooth surface. A longboard was used to identify the high spots, then the random orbit with 60-80 grit finished the rough sanding job.
The area near the longboard shows how the longboard reveals the high spots. The white areas are high. A note on safety: Because the epoxy is still green at this point - not fully cured - a good dust mask is needed when long boarding. The ROS is connected to a dust extractor equipped with a HEPA filter. Epoxy dust is a dangerous material that you don't want in your lungs. Protect yourself.
Another look at long boarding to reveal high areas. Note that the longboard was used at opposing angles in order to get the best result. If you haven't done this, check out videos on long boarding for proper technique. The more material that is removed this way, the flatter the finished product.
The double vertical line shows the overlap of fiberglass on the hull. If I had it to do over, I'd buy more glass and apply it along the hull with the overlap at the chine. It means buying more glass, and wasting some, but it would been a lot easier fairing in the long run. Lesson learned.
This is an example of where we didn't get the peel ply fully pressed into the epoxy. A little more fairing is required.
Next time we will repair a bubble in the fiberglass on one chine.
