HI I THINK the ONE guy who is complaining about ULTRA COAT must be working for MONOCOAT from my 20 years of using both- ULTACOAT is the easier to use film and will go around compound curves much better -has more fexibility therelooks more like a paint job -used some MONOCOAT just recentlyfound it the same as it always wasbought it at a swap meet-so do not know how old it was-i do not at all care for coverright materialsags on the open bays and does not hold an airfoil as it should in my opinion
