Mishap: Firing a nailgun through finished fiberglassed hull.

Post by chrisb » Tue Apr 15, 2014 1:08 pm

Hi everbody:

Today - I was seeing the end of sanding-filling-sanding-filling sanding etc etc the hull of my power skiff in order to finally paint it.
As the last action, I glued the finished floor cleats to the finished floor, temporarily fixing them with a nail gun. Despite beforehand trials as to the correct length of the nails I noticed afterwards that some of the nails must have gone through to the fibreglass, which created quite a few areas where the fibreglass was lifted off the the hull, but not actually perforating the fibreglass. The diameter of these areas is roughly 1 cm.
What should I do? Sand over and paint as if nothing had happened or take off the fibreglass from the affected areas and start filling them?
Needless to say: this is very annoying, but that's how it is!

Thanks in advance for advice.

I think that I would cut out the delaminated area. Sand the edges. Then make at patch that overlaps the hole. Sand its edges then fill coat it and sand some more.

1). Easier to fix now than later

2). It's compromised and not likely to heal itself

3). Every time you slap into a wave it will 'aggravate' that 'blister'

4). PITA now, but you'll kick yourself later if you don't fix it properly now.

5). We have all been there and done that in some way or another.

Chris-
have the "temporary" nails been removed? that would be good to do first, then grind thru one of the affected areas to see the extent of damage done. sadly something that you can not just ignore :roll:

...thanks everbody. As soon as I have stopped kicking myself for damaging the result of several weeks' labor in a couple of minutes, (...should be done by about noon ;-) ...) I shall proceed as suggested.
