For areas like a cowl and vent covers that have a lot of areas too hard to sand by hand: Would a small media blaster be okay? Speed is not crucial. I only have a Sears 5HP 20 gallon compressor so I thought I might try the HF 20 lb sand blaster.
I bought a small blaster from Grizzly Industrial. It looks kinda like a paint gun, has various rubber tips and a bag to collect the grit and dust. Actually works pretty well, but I think you'd run out of air pretty quick with a 5 gal compressor. The instructions recommend a compressor that will provide 11 CFM at 100 psi. Your 5 gal rig won't do that for more than a few seconds. I have a 5 HP 60 gal in my shop.
[on edit] The HF blast gun instructions say it consumes 7 CFM at 90 psi. Still too much for your 5 gal compressor.

If it's a 5 HP compressor, you'll probably be OK. I like the Grizzly gun I bought as it keeps the dust escape to a minimum.

We used our 2 HP Speedaire compressor to sand blast small areas. Notes: *The Speedaire is a belt driven compressor. I doubt that a 2 HP direct drive compressor will be up to the job. *A good water trap is needed installed in the line or water will clog up the nozzle. *The nozzle that came with cheap gun wore out very quickly. A good ceramic nozzle will last.
