Greetings, have been touring the site for a few weeks, lots of good info.

Just built an oven, ready to use it.

Tons of questions to start with.

1. can a person sand or use other method than aluminum oxide blasting, if sanding how fine to the sand scratches have to be for the product to bridge them. My side exhaust will not fit into my blasting cabinet.

2. What color of silver powder coating is about the same as the chromex ceramic coating for headers and exhaust. (I am not going to polish the chromex, I want a satin look, as well as for brackets and pulleys) maybe I should just use the ceramic on everything in the engine bay.

3. For heat insulation is the ceramic the best thing to use, on this cobra the foot box is only inches away from the headers.

4. How smooth is too smooth for something to be coated, can a once highly polished aluminum piece be blasted and then that be rough enough to provide tooth tooth for the powder or ceramic to bite into.

5. on my test fire I could only get the oven to 650 degrees, will this be close enough to cure ceramic.

My question is, after I go to the barn and take them out of the kiln I have to hike them back to the shop where my PC equipment is. Will I incur any significant moisture en route (and back) that will screw up my firing? It is not raining (duh) but the humidity is kinda up there.

A propane gas grill will get up to 500 in a few minutes and possibly even hotter to outgas those aluminum valve cover and intake manifolds. I don't need the precise temperature control for outgas process anyway. Is it a good idea if I can find one for cheap/free? ]]> Powder Coating Questions PoorOwner http://forum.caswellplating.com/powder-coating-questions/10779-should-i-get-gas-bbq-grill-outgas.html http://forum.caswellplating.com/powder-coating-questions/10773-did-i-ask-wrong-way.html Tue, 17 Nov 2009 23:38:49 GMT Hi, I'm a new guy here. I make custom motorcycle exhaust and am going to use Chromex ceramic and high-temp powder. So far, since I bought my supplies and joined this forum, I've asked a few questions and emailed a couple folks direct. To date, I've not gotten a single reply.

Is it my breath? Have I been impolite?

Seriously, if someone could shoot me some info I'd sure appreciate it. Here's the gist of what I'd like to know:

In my application, high temp headers, is there any significant advantage to coating with either HT powder or ceramic? I know ceramic is a bit of a thermal insulator. Otherwise, any major diffs in durability, gloss, ease of application, etc? I've got one friend that swears HT PC will eventually peel and blister. I think that is a matter of surface prep, but I dunno.

I would like a thick, maybe somewhat pebbly finish to mask minor surface imperfections. How would I achieve that?

If I shoot Chromex then buff it out with steel wool or whatever but then DON'T clear coat it, I understand it will eventually oxidize. How bad is that? Is there any reason why that couldn't be resolved by polishing the pipes occasionally with a chrome or metal polish? I might like to skip the clear coat to keep the bright 'chromey' look.

Finally, is iron phosphate a good undercoat for ceramic as well as powder?

Thanks, fellas, for your time. I know what a pain us newbies can be, but I'm trying to pay attention.

I am new to powder coating..that is, I just bought a kit and I am deciding what powders to buy here... and was in the process of designing an oven that I could build myself.

Then, I happened to trip over a Sunkiss 4101002, two head thermoreactor and I suspect things have changed a bit.

I gather I will no longer require an oven...but I don't understand how the back of an object will cure..I was told that you really only have to heat one site..the opposite will cure due to the heat of the object..

I will def'n need a laser temp gauge..

Do i just put in my garage and point it an the object that I was to coat ?

Would I be better off building an oven ?

I gather most folks are really down on Infrared Curing...and the Sunkiss is a gas powered one however, I did read a very positive comment on this board.

What do you think ?

Thanks

I make custom motorcycle pipes. I plan to coat some with Chromex and have read that if you don't clear coat them, the finish will eventually oxidize. Is that such a problem? Could they be polished back to the original look with some Mother's chrome polish or some other compound?

Motorcyclists are used to polishing their bikes, especially the chrome, so it doesn't seem to me like it would be a problem. Especially if it means you can avoid the glow-dulling effect of clear coat.

Whadya say? Any recommendations on a polish that should work okay?

What should I use at home to soak it but isn't too much of a nasty chemical?
Will simple green do it? Would it attack aluminum?

I'm new to PC so forgive me if this is a dumb question.

I need to coat mild steel parts with a high temp powder or ceramic and I need the finish to be somewhat thick or pebble-finished to overcome minor surface imperfections. If I grind/flap wheel/lab metal everything I will never get it done, so am hoping the coating can smooth things out.

I know I will have to do some of the rough work but once I get it down to minor scratches and nibs, is there a powder or ceramic coating or an additive that will help me get the look I need?

Thanks very much for your time and advice. ]]> Powder Coating Questions kent_in_kc http://forum.caswellplating.com/powder-coating-questions/10755-need-pebbly-finish.html http://forum.caswellplating.com/powder-coating-questions/10754-container-lids.html Thu, 12 Nov 2009 20:15:18 GMT Does anyone know where to get lids or identical containers for the old style columbia coatings containers.

I found a black carbide on another site but it looked too dull. They also have a 10% gloss fine texture I think may work. Who knows?
