Last year I had a bunch of fiberglass work done on my boat by an industry-well-known, long time East Anaheim boat builder, repair shop.   I've always had the best experiences at this shop in the past over many years, but this last go around has me bummed out on his service and not sure what to do now.   The boat is an 01 Commander that was always stored indoors so it was in great condition.   

This boat repair shop / boat builder did a great job on the fiberglass repairs.   Where the problems ensued was when he left the boat outside in his yard(uncovered) for months on end while the work was completed, when time permitted.   This work was done during the Summer from June until September during the hottest months.   I didn't think anything of the boat being left out as I had 100% faith in this shop's work and knowledge of what to do and not to do.   Well, as you can see the interior likely has been permanently damaged by the sun since it was left outside, uncovered by this repair shop/builder.   

I asked about this when I picked the boat up and let him know my displeasure at the interior damage, and he starting making excuses saying the boat is almost 20 years old, interior does not last forever, the damaged white interior was like that when I dropped the boat off for repair, and  so on and so forth.   Just to confirm that I knew the actual condition of the boat interior, I looked back to pictures right before the boat went in to him and can see none of the interior was yellowed- sun damaged just prior to it going in to this boat builder's shop for work.   The picture of the boat in the water is the weekend before the boat went in for work.   Lilly white interior in that picture and others from the same weekend. 

Any pros here that know how to correct this interior without spending thousands on new interior all around?   I've attached 2 pics showing the damage, but it's like this all over the boat(open bow, all seats, etc) on any surface that was pointed up, facing the sun.  I'm super bummed about this happening and think the shop/boat builder is responsible for the damage, but have yet to do anything to force the issue as of yet.    I'd just like my boat interior to be in the same condition as when it was dropped off for fiberglass work, no better and no worse.   

Anyone out there had this happen to white interior and found a way to re-condition in to look white again?    Thanks in advance.

If all else fails and you have access to compressor and a paint gun, locate an automotive paint and body shop supply store. Have them mix up some vinyl upholstery paint/dye and paint the seats, see of they can add a UV protector in the paint. If they can't have them mix a mat or semi gloss clear with the protectent. The should have something to match the gloss of the material. I have painted car seats in the past and it has held up very well. They should be able to set you up with everything you need to do the job.
