I've been doing repair work for a while now, and I do ok fairing, but there's room for improvement. I've got an early version of the Gougeon Bros book, are there others to consider?
I've been using a variety of thin plywood boards with various grit sanding belts laminated to them, as long boards. Are there official tools available? Worthwhile?
Using West's fairing filler usually leaves me with tiny pinholes that requires a lot of primer to fill, and not always successfully. My bodyman has recommended Dolphin glazing compound, which works well. But I wonder about it's long term compatability with epoxy, 'cause I'm pretty sure it's a polyester base. No problems so far, used under Flight Risk's automotive paint, now 4 years old and looking great. Anyone else have experience with similar products? Or techniques to deal with the pinholes?
Other sage advice?
Thanks of always!
