Seeking replacement blades Windseeker 503
I am looking for a source for replacement blades for an old Southwest Windpower Windseeker 503. My 24v model came with with the upgraded carbon impregnated polypropylene blades, hub, and nosecone. Any help would be appreciated. If unable to secure replacements, would it be possible to perhaps paint the 15 + year old blades to repair sun damage?
