Deep scratches, gouges, and spider-web cracks are more than surface problems — they expose the hull to water intrusion. We assess penetration depth before we quote, because what looks cosmetic sometimes goes deeper.

Gel coat is the hull's first line of defense — a relatively thin layer over the structural fiberglass beneath. A scratch that reaches through gel coat into raw fiberglass opens a path for water. In Michigan's freeze-thaw climate, that water expands, the damage grows, and what started as a cosmetic issue becomes structural.
We assess every scratch before quoting — depth, width, and whether the fiberglass underneath is compromised. That assessment determines the correct repair approach. Filling over a scratch that's reached raw fiberglass without addressing the substrate is a repair that will fail.
Our goal on every cosmetic repair is a finish you can't find with your hand. That requires the right process, not just the right product.
We evaluate whether the damage is gel coat only or has reached the fiberglass substrate. This determines the repair method. Running a fingernail across a scratch tells part of the story — we look at the scratch profile, the color of the material at depth, and whether the surrounding surface shows stress.
If fiberglass is exposed, it must be treated before any filling begins. Contaminated or damaged fiberglass won't bond correctly, and a repair that doesn't bond will fail.
Gel coat or appropriate filler applied in layers, built up to slightly proud of the surrounding surface. Faring — sanding back to flush — is where the invisible finish is created. This step takes patience and can't be rushed.
Gel coat mixed to match the surrounding hull. Same process as our full restoration work — matched to the aged hull, not the original factory code. Honest best effort, as documented in our service agreement.
Compound and polish to bring the repaired area to gloss matching the surrounding surface. The transition zone between repair and original surface is blended until the boundary disappears.

Hardware store gel coat kits are formulated to bond to themselves, not to marine fiberglass. If a previous repair attempt used the wrong product, removing it correctly before we can work is additional time and cost. It's not a disqualifier — it's just part of the honest estimate.
Tell us upfront if a prior repair has been attempted. We'll assess it at intake, tell you what it means for the repair, and quote accordingly. We've seen everything — no judgment.
All workmanship is warranted for 90 days from service completion. If a defect in our work is identified within this period, we return to correct it at no additional charge. This covers workmanship only — not impact damage, improper use, or conditions outside our control.
