Should’ve shown how you were going to reattach that baffle

Another thing, avoid sandblasting magnesium valve covers. I did mine not knowing it was magnesium and well, the casting was ROUGH. Lots of pitting and casting flash was hidden by the factory coating and it looked horrible. I spent quite some time fulling pits with JB Weld and grinding down casting flash. Even after I was done it still didn't look quite as good as the factory coating did when new, even using wrinkle paint.

That's why you use paint stripper instead, no reason to sand blast

Did powered coating for YEARS! You do NOT blast under the valve cover! It makes it too rough and oil collects, burns, and then bakes on gumming it up. Just do a good job taping and washing before paint and you'll be just fine.

Soda blast is better for engine parts
