🚤 Garage Project – Corvette & Boat Restoration Planning Summary

Prepared for project documentation and future expansion.

📌 Overview

This document summarizes the discussion on using the new garage for DIY automotive restoration, boat maintenance, winterization practices, and long-term project workflow planning.

🏎️ DIY Automotive Paint Booth Feasibility

Conclusion: Yes — a person with solid handyman skills can absolutely build a functional, high-quality DIY automotive paint booth in the new garage.

Key Points

  • Your 24’×40’ garage with high ceilings, great insulation, hydronic heat, and future mini-split is ideal for a paint booth setup.

  • A temporary booth (~$1,500) using PVC or 2×4 framing + 6-mil plastic + filtered airflow is realistic.

  • Proper booth requires:

    • Intake filtration
    • Explosion-proof exhaust fan
    • Strong LED lighting (CRI 90+ preferred)
    • Controlled airflow (crossflow or downdraft)
    • Clean prep area (epoxy floor, sealed walls)

  • DIY paint quality can reach “very good driver quality” to “near-show quality” with good prep and wet sanding.

💵 DIY vs Professional Paint Job Cost Estimate

DIY Paint Job Total: 4,000

  • Paint booth setup: ~ $1,500
  • Primer, basecoat, clearcoat: 1,000
  • Tools, guns, consumables: 600
  • PPE + safety gear: 400
  • Higher-end guns or compressor upgrades may increase cost

Professional Shop: 12,000

  • Typical price for a quality repaint on a classic Corvette
  • Higher-end/show-quality can exceed $15,000
  • Pros: time savings, guaranteed quality
  • Cons: high cost, less flexible for incremental improvements

Savings with DIY:

Approximately 8,000 while gaining valuable skills.

🧰 Long-Term Corvette Hobby Restoration Plan

You prefer a “drive it and improve it” approach rather than turning it into a show-only car. This is perfect for DIY restoration.

Suggested Project Phases

  1. Exterior paint refinishing (Bay 3 paint booth)

  2. Interior refurbishment

  3. Engine bay detailing & repaint

  4. Rust removal & bead blasting small components

  5. Chrome restoration:

    • Polish existing chrome
    • DIY spray chrome
    • Home plating kit
    • Professional rechroming (for large or highly visible parts)

Advantages

  • Keeps the car enjoyable to drive
  • Allows incremental improvements
  • Each winter becomes a dedicated upgrade season
  • Tools and paint booth gain future utility for other vehicles

🏗️ Three-Bay Garage Workflow

  • Bay 1: Wife’s daily driver (clean storage)
  • Bay 2: Boat (MasterCraft Maristar 210) — dedicated indoor storage
  • Bay 3: Full-time restoration/work bay with automotive lift

Key Flexibility Points

  • Corvette can be moved outside temporarily when lift access is required
  • Toolboxes/workbench on casters enable modular layouts
  • Diesel heaters provide backup heat
  • Bay 2 (boat bay) remains stable and uncluttered year-round

❄️ Should the Boat Be Winterized Even in a Heated Garage?

Strong Recommendation: YES. Even with:

  • In-slab hydronic heat
  • Natural gas boiler
  • Natural gas backup generator
  • Diesel heaters
  • Excellent insulation

Winterization is still essential.

Reasons

  • Winterization protects against catastrophic damage if any single system fails.

  • Only 1–2 hours of below-freezing temps inside the block can crack:

    • Engine block
    • Manifolds
    • Heater core
    • Transmission cooler

  • Indoor heat reduces risk but doesn’t eliminate it.

  • Cost of winterization: ~50 and 1–2 hours

  • Cost of freeze damage: 10,000+

Winterize every fall — it’s cheap insurance.

🚤 Boat Winterization Best Practices

Cooling System

  • Pull raw water intake hose off the pump in the engine bay (no need to access the through-hull under the trailer bunk)
  • Drain block, manifolds, and transmission cooler
  • Bucket-feed 3–5 gallons of pink marine antifreeze until it flows out the exhaust

Oil

  • Change oil during winterization to remove acidic contaminants

Impeller

  • Replace in spring, not fall (prevents deformation during storage)

⛽ Fuel Storage Recommendations

Fuel handling is critical for winter storage.

For Ethanol-Blended Fuel (E10):

  • Store with a FULL tank
  • Add marine-grade fuel stabilizer (Sta-Bil Marine recommended)
  • Run engine 5–10 minutes to circulate stabilized fuel through system

For Ethanol-Free Recreational Fuel:

  • Still use stabilizer
  • A full tank is safer but not strictly required

Why Full Tank?

  • Minimizes air volume
  • Reduces moisture absorption and condensation
  • Prevents ethanol phase separation
  • Protects injectors, carb bowls, and pump seals

📅 Seasonal Routine Summary

Fall (Winterize):

  • Add stabilizer → fill tank
  • Run engine to circulate treated fuel
  • Drain cooling system
  • Bucket-feed marine antifreeze
  • Oil change
  • Stabilize battery
  • Clean interior
  • Cover and store

Spring (Summerize):

  • Install new impeller
  • Top off fuel
  • Inspect belts/hoses
  • Start engine and check cooling flow
  • Clean hull and interior
  • Launch and enjoy

✔️ Final Notes

  • Your garage design, heating infrastructure, and three-bay workflow are exceptionally well suited for both Corvette restoration and boat maintenance.
  • You are thinking exactly like a professional marine/auto tech — your approach is methodical, safe, and optimized for long-term reliability.
  • This will become one of the most capable and enjoyable hobby garages imaginable.
