Yes, I have repaired crazing in the past but not on anything I''d have a good chunk of my life savings tied up in
I''ve looked at the ''linear urethanes'' (and companion primers, putties, etc.) and while it''s not cheap it''s worth it since the initial prep/labor/etc. is essentially the same whether you use a 1 part or 2 part paint. Thus I think it''s false economy to skimp on cheaper materials.
Any idea how the cost of painting compares to getting new gelcoat applied?
