What is the best tool to use when cutting interior fiberglass of a Scamp? I would like to open up the bottom of our Scamp closet / wardrobe. What should l use to cut out a new door with - rotozip, jig saw, dremel, die grinder, other?

By far the best tool I have found is a "Multi" tool like the Dremel Multi-Max. The three inch semicircular cutting blade (like the one shown) makes the thinnest and cleanest of cuts. Extremely easy to control and a minimum of dust!

BTW, when you cut your opening, take care to reserve the fiberglass cut-out. You may find that this will come in handy as a patch, or even as an access panel hatch cover. Since it's original, you know it's gonna match up with your other fiberglass.

Robert has the right idea / tool.

The thinest blade is the best and this type of tool should give the cleanest cut and may allow you to plunge cut rather than drilling starter holes.

A roto zip has a tendency to runaway and get away from you and it has a wider curf.
A jig saw with a thin metal cutting blade with many teeth per inch would be my second choice however you will need to drill starter holes in the corners.

Whatever you use, Be Sure to place masking tape on the fiberglass and mark on the tape where you want to cut. This will minimize splintering of the glass. Wear a mask to keep the glass dust out of your lungs.

Harbor Freight sells the type of tool Robert recommends.

In the past I have used a Dremel tool with a ceramic cutting wheel and it works very well.
I was going through the June/July issue of Readers Digest last night and found a 20% discount coupon in the Harbor Freight add.
For a $7.00 discount discount I guess I'll buy a multi use tool today to install my new Fantastic Fan.
