I have completed fiberglassing a fuselage with 3/4 oz. cloth and water-based polyU. Everything went fairly well. Two questions. I have a couple of creases and seams that I did not do a very good job on. How do I remove them by sanding down to the level of the main fiber or ssanding to the wood and ppatching with fiberglass.
>Sand to the level of the main fiber and patch with lightweight
>filler. Don't forget to give it a coat of poly after the sanding is all
>completed.
Second what kind of filler do I use to get ridd of high and low spots?
>Use lightweight filler - lightweight spackle, Hobbico Lightweight
>filler, etc. Again, don't forget to give it a coat of poly after you
>have completed the sanding. Most of the fillers will soften and/or
>disolve if subjected to water or the chemicals in paint/thinner.
Be advised that waterbase poly is FUEL RESISTANT, not fuel proof. If you let a clear coat dry for a minimum of a week AND wipe your plane down at the end of the day you should be OK. If you let the residue sit on the plane for several hours it will soften the poly.
Here is a "How To" on using water base poly for glassing. This is all stuff I learned "the hard way"
