Not Ranked
for laying up a small area I have used strips of brown parcel tape to stop the glass matting sticking to the area I was moulding onto - fibreglassing onto the non-sticky side. Just peels off aftwards when the fibreglass is dry. Cheap and easy, and forms a smooth finish. Occassoinal dinks (caused by air bubbles and my cr*p skil level) can be filled later with body filler and sprayed over. Have to say i think ali would be an easier option here, if it can be fitted neatly round the aperture.
cheers,
Kevin
