The Hidden Cost of Chemical Stripping: A 27-Day ROI Analysis

The Setup

The shop in question is a small-to-mid-size general aviation MRO with three full-time A&P mechanics, a hangar bay that handles roughly 80 aircraft per year, and a chemical stripping operation that had been in place for over 15 years. The owner agreed to share the financials — anonymized — to give other shops a real number to compare against.

Year-Before Costs (Chemical Stripping)

Materials

• Methylene chloride strippers: $3,750/month → $45,000/year
• PPE (chemical suits, respirators, gloves): $667/month → $8,000/year
• Hazardous waste disposal: $1,250/month → $15,000/year

Labor

• 3 technicians at $30/hour fully loaded = $90/hour
• 2,000 hours/year on stripping operations → $180,000/year

Overhead

• Insurance (pollution liability rider): $12,000/year
• Permits and compliance fees: $5,000/year
• Ventilation utilities (5,000 CFM continuous during strip): $18,000/year
• Downtime / customer delays: $75,000/year

Hidden Costs (often missed)

• One worker comp claim every 18 months: average $15,000
• One EPA inspection follow-up: $25,000 in unplanned compliance work
• Customer losses (reputation): conservatively $50,000+

Total Annual Cost of Chemical Operation: $358,000

Year-After Costs (FP-300 Operation)

One-Time Investment

• FP-300 system: $18,600
• Operator training and certification: $1,500
• Accessories (ducting, additional safety eyewear, IR thermometer): $2,000
• One-time investment: $22,100

Year 1 Operating Costs

• Labor (1 technician, vs. 3 — the laser is faster than 3 chemical operators): $60,000/year
• Consumables (replacement protective windows, lenses, IR sensor): $2,000/year
• Filters (pre-filter, HEPA, activated carbon): $1,200/year
• Maintenance (calibration, scheduled service): $3,000/year
• Utilities (laser draws less than the chemical ventilation): $1,800/year

Year 1 Total: $90,100

Year 2+ Operating Costs

Same as Year 1 except for slightly higher consumables and maintenance: $68,300/year

The Math

Previous annual cost	$358,000
FP-300 Year 1 cost (incl. equipment)	$112,200
Year 1 Savings	$245,800
FP-300 Year 2+ cost	$68,300
Year 2+ Annual Savings	$289,700
Payback period	$22,100 ÷ ($245,800 / 365) = 33 days

Note: the often-quoted 27-day payback comes from a different shop where labor was the dominant cost. Payback period varies with the cost structure of each shop, but no FP-300 customer to date has reported a payback longer than 60 days.

Cost Per Square Meter Comparison

Normalizing to a per-area basis to compare against media blasting, which has different cost dynamics:

• Chemical stripping: $85/m²
• Media blasting: $65/m²
• FP-300 laser: $12/m²

That 5–7× cost reduction per unit area is the structural advantage of the laser process: no consumables proportional to area cleaned, no waste stream proportional to coating removed, no setup/breakdown time per job.

5-Year Projection

Year 1 savings	$245,800
Year 2 savings	$289,700
Year 3 savings	$289,700
Year 4 savings	$289,700
Year 5 savings	$289,700
5-year total savings	$1,404,600
Initial investment	$22,100
5-year ROI	6,355%

Soft Benefits (Excluded From the ROI Above)

The numbers above don't include benefits that are real but harder to quantify:

• Faster turnaround: Aircraft return to service 2–3 days sooner; customer satisfaction up
• Quality: Fewer warranty repaints; better surface prep; more confident A&P signoffs
• Recruiting: Younger technicians prefer laser work over chemical exposure; turnover drops
• Insurance: Some carriers offer pollution-liability rebates for media-free shops
• Future-proofing: Insulated from tightening environmental regulations on hexavalent chromium and methylene chloride
• Marketing: Customers explicitly ask for laser-based shops in some segments

Risk Factors to Honestly Consider

Not every shop sees the same numbers. The biggest variables that can change the math:

• Existing capital sunk in chemical infrastructure: If you just installed a $200K wet-blast cabinet, the depreciation will hurt the comparison
• Volume: Shops doing fewer than 30 strip jobs/year see longer payback periods (still under 6 months in most cases)
• Customer mix: If your customers specifically want chemical stripping for some reason, you may need to maintain capability for both
• Operator training: Shops that under-train operators see slower productivity gains; the 16-hour basic certification is the minimum

How to Run This Analysis on Your Own Books

Before deciding, pull these numbers from your own records for the past 12 months:

1. Total chemical/media purchases
2. Hazardous waste disposal invoices
3. PPE replacement costs
4. Hours per technician spent on stripping operations (timesheet review)
5. Insurance premium specifically attributable to chemical operations
6. Number of lost-time incidents related to stripping
7. Customer downtime credits or refunds related to stripping delays
