going through the exact same thing - engine is out - want to clean and paint underneath it.

Any recommendations on not-too-toxic cleaners, that would remove 30 years of grease and grime, and not damage the fiberglass, before I sand lightly and paint?
The engine area runs under a fake floor, to the main bildge, which is a greasy mess as well.
I was thinking of an orange / citris based cleaner, as the orange hand cleaners remove bike grease, etc quite well. Possible a spay bottle type, from an industrial supplier??
Other suggestions??

Oops! I ment to post my previous response to the guy who owned the C36 with a heat exchanger problem. You should be able to disassemble your bulkheads too for easier access to the area. No matter what you do, you need to clean the area really well as these types of products don’t stick well to greasy surfaces. Make sure the surface being covered has a little “tooth” to it. I have had success with spraying white gelcoat over a masked off area. I use one of those throw-away spray bottles you get at the home stores and thin the gelcoat with a little acetone. On your flat bulkhead surfaces, have you considered using some de-coupling sound insulation? I remember reading somewhere that properly vented engine compartments should have an ambient air temperature no more than 120 degrees F so any barrier coating or gelcoat should work fine.
