How do I prep my engine for paint?
I will soon be painting my motor for my KX-DX hybrid project, and I'm wondering the best way to prep the cases, covers, etc. Despite 45 minutes of Simple Green and a pressure washer, there is still a lot of baked-on mud residue that I can't really scrape or scrub off.
I thought about plugging up all the holes and getting a little gravity-fed sand blaster to hook up to my air compressor and just blasting the motor in the yard, but someone knowledgeable in the gearhead ways tried to dissuade me from that, saying no matter how careful you are, you're going to get blaster media in the seals and gaskets. I am hoping to avoid a bottom-end rebuild with this project, so I defnintely don't want to have to split cases to clean out sand from the sandblaster.
Anyone have any experience with this? Would using a softer media, like crushed walnut shells, be less likely to get in the seals? Is it really even an issue?

I was going to suggest the Sandblaster, but have you tried a Wire Brush on a Drill or Engine Degreaser & a Hand Held Wire Brush.

Why do you want to paint it?
I used Krud Kutter, wire brushes, wire wheels, carb cleaner, you name it on my motor this winter
Wish I'd taken a before pic, the motor was stained kinda tannish orange with the red clay I ride on

For painting, you should create a "toothed" surface by grit blasting with alum oxide or similar. You could do it on an assembled motor with the sufficient prep.
Even without the blasting, lots of guys on the CBX forum paint them as assembled. Usually cleaned, but not blasted.
For cleaning, try soda blast:

Hmmm...that homemade blaster was cool. Do if you blasted your engine or hubs, would you need to pud a protective coat on them afterwards? By blasting are you blasting away a factory protective coat?

I tired the homemade soda blaster in that link on a rear hub and it cleaned it very well.
It wasn't a big deal, but the baking soda didn't feed through the tube at a consistent rate. I'd have a second or two of soda coming out, followed by a second of air, then a second or two of soda, etc.
The rain then cleaned off the driveway and you couldn't tell anything was done on the driveway.

Did you use the recommended giant air compressor. I only have a little pot belly model and I'm sure it wouldn't produced the required volume.Tedh98 wrote:I tired the homemade soda blaster in that link on a rear hub and it cleaned it very well.
