After outgassing your part it is important to lay down a primer to minimize outgassing...this applies to cast parts only. If you wish for additional corrosion resistance, please ask our advise for there are better options....do not lay a basecoat or primer just because. It is a waste of your time and resources!

Re: WHEN COATING CAST PARTS
What about extruded parts? I deal with a lot of parts made from a billet of 6061 and I outgas everything - to remove anything in the substrate itself as well as burn off any fluids that may still be present from the machining process. Generally, my procedure is: achieve base finish/polish/deburr/etc, clean with soap and hot water, dry, wipe with acetone, outgas, clean with alcohol, shoot color coat, cure, clear/cure if needed.
As for cast parts, I have an aluminum intake and a carb to do in the next month of so. Should I prime the intake before color coats?

Re: hello
Zinc primer is good for chemical corrosion.....the problem with acetone is that if it gets into any nooks or cranies and does not evaporate, it could blow! not so good for your oven ...Originally posted by DxCComment

Re: WHEN COATING CAST PARTS
Since Aluminum does not (or should not) rust that substrate should not be treated for any corrosion resistance. Don't you agree?Comment

Re: WHEN COATING CAST PARTS
The problem a custom coater will run into with the aluminum is that you need additional fluoride in your iron phosphate to bite into the aluminum and shipping on these products high due to the fact that fluoride is hazardous...anyone have Crest ? So, in essence the powder will protect the part from the environment and white rust depending on the application. Now, if the client has a part that is Architectural certain pre-treatment chemicals and dry in place sealers are recommended. Also, there are products that you can use that will give you a five year warranty, or you can use a 100% Fluoropolymer that will give you a 15 year warranty but you must be approved by the manufactuer of the powder before you can purchase.Comment

Re: WHEN COATING CAST PARTS
Right here. Since I don't have have the pretreatment capability of Harleydad, I couldn't do any of that architectural grade stuff either.

Re: WHEN COATING CAST PARTS
I'm in no hurry for snow unless it snows at ninety degrees!! Winter sucks too cold, I hate it when it's colder outsid than my beer. Women wear way to many clothes. Your trapped inside the whole time.
Ya see I like summer nice and hot. The beer taste better, women are half naked, theres more to do outside. You can go cruising and check out the hott half naked chicks.
