Re: Cleaning an early aluminum intake
Have you seen the finish vapour blasting gives? Looks like brand new!

Re: Cleaning an early aluminum intake
.
I've gotta say WOW! That came-out pretty damned clean, yet still retains that factory-cast sheen which is destroyed via bead blasting. Bead blasting gets 'em clean, but they never look the same as when NEW! Have you got a brand name of that product? Available at boat supply outlets? DD |

Re: Cleaning an early aluminum intake
With respect, how does anyone know 'exactly' what the factory-cast finish looked like? Not trying to be argumentative, but exactly which of the above pictured finishes exactly matches that of a brand new casting? And how does one verify this?
I still maintain that a vapour blasted surface produces an 'as cast' finish. The problem is maintaining that 'as cast' appearance. Aluminum, by virtue of being that element, soon tarnishes/oxidises just by being in contact with the atmosphere. So, it ends up looking somewhat like the above picture portrays, however, that ain't what it originally looked like! IMHO

The manifold below is a known NOS unit. The surface has an obvious, smooth sheen that can't be duplicated after bead blasting. This manifold below has been bead blasted. It is certainly clean, but the surface is dull with bazillions of little imperfections where the beads have 'moved' or distorted the aluminum finish making it microscopically 'rough' as compared to original. ................. |

Re: Cleaning an early aluminum intake
Soda blasting is another option

Re: Cleaning an early aluminum intake
The Marine hull cleaners I used were On & Off marine hull cleaners by Marykate ?, and Star Brite marine bottom & hull cleaner. The Star Brite seemed stronger than the On & Off, nut may heave been because it had been on the shelf longer. If anyone is considering this method, clean as much of the oily sludge off the part, and caked grime in corners 1st, do it outside in a well ventilated area, stay upwind, wear gloves & eye protection, and have a fresh water hose handy. You will probably like the results, but not the process. Takes about 2 hours all tol

Re: Cleaning an early aluminum intake
I'm lazy. If they're pretty bad. I bead blast them and find the best looking aluminum paint and paint 'em. I get a lot of positive comments at our local car shows. (I'm glad that you guys don't live up here.)

Re: Cleaning an early aluminum intake
For the pessimist's information the marine hull cleaner didn't touch the Ford Aluminum manifold. Maybe some type of aluminum but not a Ford casting in my experience.

Re: Cleaning an early aluminum intake
A vapour blasted intake would look damn close to that nos one of coop's.

Re: Cleaning an early aluminum intake
You could also blast the parts with glass pearls - this will give it some shine. Or get the parts tumbled, depending on the used stones you could decide what finish you get. Or do as I do and brush the parts after glasspearling - looks very much as just cast.

Re: Cleaning an early aluminum intake
I have blasted aluminium and then gone over it with fine wire brush in a drill motor and that gave it a look very sim to that NOS photo above.
