What??? Just about anything metal

And "Media Blasting" and or "Bead Blasting" What the???
Media blasting can be ash, soda... lots of soft stuff. Bead blasting is usually glass, media is easier on the metal.

Sounds like you need to prep the blasted parts better. Sorry about the wife [img]/phpBB/images/smiles/icon_smile.gif[/img]

I have to agree with qtrmiler, sounds like the parts need better prepping after the blasting if you are not getting adhesion from the paint. Are you washing down the parts with a solvent to degrease them? If so, are you washing them off with hot water afterwards to remove all residue?
What I do after stripping my parts (either chemically or blasting is to wash them down thoroughly with hot water to remove any and all dust, or body oils, and then toss them in my old oven for a bit at about 350 degrees to dry them off before any rust spots start to flash.
Good luck!

You might nog get what I said!!!

I said my sandblasting is "next to none" IE. The BEST! can't be beat... I NEVER have problems with adhesion of paint nor are ther any problems after finishing a product.

I want to know the diffrence between these and or the benefits of say... Media Blasting VS Sand Blasting... and What the Heck is powder coating in it's definition.

That's what I ment to say...

Powder coating is just that, spray on power & bake it & it becomes a tough finish in one of several colors. Media blasting just keeps a lot of heat out of the body panels, saves shrinking the metal.

Sorry I misunderstood what you meant there.
But yes powder caoting is what it sounds like, a powder is postively charged, and the item (being metal) is negatively charged. This creates the adhesion of the powder to the item, then the item is baked in an oven and the powder then "melts" covering the item.
You need to look into it carefully, there are two types of powder coating. One version is thermosetting, where the powder chemically changes at high temperature, bonding to the metal surface, and then it sets. It will not "remelt" when brought back to high temps again, and is a very durable finish.
I can't remember the name of the other version at this moment, but basically it is when the powder is brought to high temp, it melts and covers in a sort of shell over the metal, not good for most applications as it can be peeled off, and doesn't hold up well under conditions outside. This is the type many people have had, when you hear of them complaining about it not being a durable finish. This version is not as common any more.
It's amazing what you can achieve with powder coating, the color selection is getting better all the time, and the metallics are cool. Even the chrome finishes are getting good, looking very respectable at all but up close scrutiny. Eastwood is a good supplier of the powders for small use. But if you are thinking of larger scale operations, Dupont is a good one to start with.

Yessssss, that is what I wanted to hear! Thank you a berzillion! I am a Dupont user now-a-day's anyhow, but I think that until someone specifically asks for it I'll keep on keepin' on.

Thank You Very Generous Souls for you Input![img]/phpBB/images/smiles/icon_tup.gif[/img][img]/phpBB/images/smiles/icon_tup.gif[/img][img]/phpBB/images/smiles/icon_tup.gif[/img]
