Shane at Divine replaced the Fusion stereo and speakers on my boat. He did an incredible job guiding me to the right solution and then doing the install. He was mobile so the experience was quite convenient and the workmanship was of the highest quality. In addition, he gave me recommendations to other service providers to do repairs on my boat. My experience was terrific and I highly recommend Shane and Divine.

Shane was great! Very knowledgeable about audio and electronics, great suggestions for products. Best of all, he picked up my boat and returned it the very next day with all new sound system! Really happy with the update so far!

Shane is wonderful to work with. He put a much needed upgraded sound system on my yacht in Lake Union and some other nice gadgets. Beautiful workmanship.

Know The Damage
What We See On Puget Sound Boats
Damage that sits gets worse and more expensive. Here is what usually shows up and why it matters.
Gelcoat Chips & Scratches
Gelcoat is the shiny layer that gives your boat its flair. Once it chips or weathers away, the laminate underneath starts taking on water.
Fix Early, Before The Core Gets Wet
Spider Web Cracks
Hairline fractures caused by hull flex. Common on 1970s era boats with thick gelcoat layers that cannot tolerate any movement.
Cosmetic Now, Structural Later
Blisters & Osmosis
Roughly one in four fiberglass boats gets gelcoat blisters. The repair means removing all damaged laminate, drying the hull, and barrier coating.
Dry, Grind, Barrier Coat, Done Right
Dry Rot In The Core
Even fiberglass hulls have wooden stringers and studs. Humidity, poor ventilation and winter storage all speed rot along.
Immediate Action Required
How Our Fiberglass Repair Process Works
Proper fiberglass repair takes skill, patience and the right materials. We follow a proven process so every repair is as strong as the original factory lay up.
Thorough Inspection
We assess the full extent of the damage, including hidden structural issues beneath the surface that a quick look would miss.
Damage Removal
All compromised material is carefully cut away to expose a clean, solid foundation for the new lay up.
Fiberglass Lay Up
Layers of marine grade glass fabric and resin are applied and built up until the repair area is flush, solid and as strong as factory.
Sanding & Surface Prep
The area is methodically sanded and faired to a smooth, even finish ready for gelcoat or paint.
Gelcoat Or Paint
Precision color matched gelcoat or high gloss marine paint sprayed and buffed so you cannot tell where the repair ends.

Fiberglass Repair FAQ — Seattle
Common questions from Puget Sound boat owners about gelcoat and fiberglass work.
How much does fiberglass repair cost in Seattle?
Cost depends on the size of the damage, whether the core is wet, and how much gelcoat spraying and buffing is needed. A small scratch respray is a very different job than a transom rebuild, so every quote starts with an on site estimate.
Can you match my boat's gelcoat color?
Yes. We tint gelcoat to match your hull, spray it, then wet sand and buff the area so it blends into the surrounding finish. Faded older hulls take extra care, and we blend the repair out rather than leaving a hard edge.
How long does a fiberglass repair take?
Cosmetic gelcoat repairs are usually a few days. Structural work like transoms, floors and stringers takes longer because the laminate has to cure properly between stages and any wet core has to dry fully before we reglass.
Are spider cracks a structural problem?
Not usually. Spider cracks are non structural damage to the gelcoat caused by hull flex, and they are common on older boats with thick gelcoat. They should still be repaired because water works its way into the laminate through them.
Do you repair blisters and osmosis damage?
Yes. We grind out all damaged laminate, dry the hull thoroughly, then apply epoxy barrier coats. Keeping the bilge dry, adding ventilation and checking the barrier coat annually all slow blisters from coming back.
Do you work on things other than boats?
We do. Motorhomes, personal watercraft, truck hoods, hot rod bodies and custom fiberglass fabrication all come through the shop. If it is fiberglass, we can repair it.
