Why sand blast? If the paint on your engine is peeling in some areas, just scrape and sand smooth. Sand blasting will leave a rough profile on the aluminum (unless that is the look you are going for).Here is a thread on when I swapped out my engines. I took the new to me dirty, peeling engine and cleaned it up, repainted and installed. 2 1/2 years later the paint is still glossy and looking new! I used Duplicolor engine paint, 2 coats and while the second coat was tacky I sprayed Duplicolor high heat clear. After the paint dried on the surface, I ran the engine till hot & baked the paint on the rest of the way. Take a look and you be the judge!viewtopic.php?p=4403#p4403
