Over the past week I've been sand blasting the engine compartment.
First I built a catch system to re claim the media. Or at least most of it.
I'm using Aluminum Oxide with a Harbor Freight Pressure pot. I go thru ceramic tips pretty fast. Set at 100 PSI. The compressor is screaming full speed while blasting. Thus I have to take breaks once in a while to let it catch up.
Overall it's coming out good just not as fast as if I sent the whole chassis out. Weather is cooling now to make it worthwhile staying out.
Afterwards, I DP'd the compartment.
