Thanks McCreed

I feel better about being verbose !!

We didn't put any metho or such on as the grain hadn't raised. Good point about too fine a grit and I'll note that for next time.

The bubbling only happenend after the wet and dry process and only around the penetrations so I am assuming water has crept under one or some of the layers of primer, paint or clear coat. I have sanded the clear coat off and starting again. I have sealed the small screw holes with pva glue and coated the insides of the large holes with pva as well ( and crossed my fingers ).

I'll let the group kmow how this goes.

Thanks for the support
