I have finally bought suitable protection mask for drilling fiberglass so can now get on with cutting out parts of the body. It didn’t take long once I worked out what I would do. I decided to drill holes and then use the dremel to cut through and finish the edges. It worked very well, but care is needed as the dremel can really go through the body at a rate of knots if you don’t concentrate!

Drill the panel first

Cut out and finish with dremel

Took longer in prone position!
