Re: Aluminum metal pretreatment.

There is two versions of alodine- a clear treatment and one that leave a tan colour, for me with powder coating I intend to cover with a solid colour so it doesn't matter.

Re: Aluminum metal pretreatment.

For aluminum, Alodine is suggested as a surface prep for coating or painting. For ferrous metals, manganese phosphate or zinc phosphate is suggested as a surface prep. I wanted to move over to the topic of ferrous, as with the other chem- fresh after clean/blast I want to mist a chemical on at room...

Re: Aluminum metal pretreatment.

I don't see how a plater has anything in common to what I'm doing? I don't have bathes either.

Re: Aluminum metal pretreatment.

I purchased an oven and the basics years and years ago and it's been sitting in a corner, big enough to do a harley frame and maybe a few rims at a time. Locally there is demand and maybe later ceramic coating as well. Hopefully more a hobby that pays for itself. And yes buying the supplies at my sc...

Re: Aluminum metal pretreatment.

This was also suggested. Started out promising- but it looks like it requires a rinse- which is an issue for me due to water quality.

Re: Aluminum metal pretreatment.

That Alodine and several other chems are nasty stuff. It is available in Canada, $cdn130 shipped for 1 gallon. Does it perform? Anything that would work well for ferrous/non ferrous to cut down on chemical stock? https://www.aircraftspruce.ca/catalog/cspages/alodine1201.php I think the surface textu...

Re: Aluminum metal pretreatment.

Thanks for the replies, situation is small town alberta so shipping is an issue with many usa products simply not available or uneconomic. Still need to visit napa and a northern metallic location. Ideal parameters would be a safe solution to apply by spray directly after blasting at room temperatur...

Aluminum metal pretreatment.

Metallurgy question, getting into powder coating and have a run of alum rims to do. Power washing most junk off before having sand blast done- but to halt alum from oxidizing and to prepare the surface directly for coating, what have you guys used in a similar situation?

Re: Best 70’s vintage SBC build.

The OP is getting much the same answers as the 'other' thread that were apparently upsetting.
The 'other' thread's parameters were period correct 70's factory/modified parts for 600hp and 11sec in a 1977 camaro.

I'll say no more.

Re: Building an 11 second 70's nostalgic SBC

Ummmm.......stil is an excellent and informative site----> but the questions have to be competent, and a mind has to be open to other points of view. These qualifications seem to be absent here. Maybe a better initial question would be: What was available in the late 70's ('77) to build XXXhp sbc, p...

Re: Building an 11 second 70's nostalgic SBC

Why? Because nostalgia isn't your thing? Sorry to say, but at a car show, talking about the car, I would be much more interested in hearing about a nostalgia built old school 350-400 than an LS swap. It isn't a racecar and it doesn't need to have the latest and greatest stuff in it to be cool or be...
