Ceramic can be used for many different engine components such as Piston skirts, piston tops, exhausts intakes...etc.

Once powder is fully cured none of the above mentioned liquids will affect the powder with the exception of the Lacquer Thinner as it will soften the powder.

Thanks for your responses. Much appreciated.

I recently restored some Honda Comstar rims for a custom bike build.

Finished up some exhaust headers. Here's one of them.

I have always been curious. When one powdercoats, whats the best way to get a "thick" coating? I know that the initla layer is due to electrostatic cling. But, does that attraction of powder to metal continue once the initial layer goes down?

I do some rare powdercoating at home, and it seems once you put a thin layer down, the powder is no longer really attracted to the part. And thin podercoating seems to scratch pretty easily.

Also, how the heck do you get powder into the small nooks and crevices? Due to the Faraday effect, the powder just doesn't seem to go there...

Hey Bo,

Thanks for the question. To answer your question, yes the attraction of powder to a base layer is certainly achievable. There are to reasons why multiple coats of powder cause a problem for hobbyists and DIY'rs.

First, and most important, you must have a good ground. If you sprayed your first coat and then try to spray a second or multiple coats you must have a spot on the piece to be coated where the metal is bare and still making a good ground. Sometimes I need to use a file to clean up powder where the hook will hang before I spray the next coat.

Secondly the Powder Spray Gun that is being used plays a huge part in being able to apply multiple coats. With most hobby guns you can not adjust your amperage and or KV which is necessary in spraying multiple coats effectively. This also holds true for "Faraday Area's".

Hope this helps. Let me know if i can help you out with tricks or tips so you can get those multiple coats down.

Finished up a BMW E30 Valve Cover in Splatter Black

Nice stuff. On that BMW valve cover, is the raised area bare aluminum that's been cleared with PC, or is it colored (silver)? Thanks, John

The raised letters are bare aluminum but they can be done any which way.

Yes we decided to use a metallic gold for the dust shields.

I've had great results with VariPrimer (self etching primer) then simply top coat with paint of your choice. I have door handles done years ago this way that still are perfect and no nicks on them! Cheap simple to do in any garage and looks like paint but very durable. I've also done wheels this way and they hold up very well and never crack and don't chip easily either. The trick is the self etching primer that chemically etches to the metal surface.

Few links with details:
Transbond
Eastwood Self-Etch Primer Gray

The reason it works well is it will not allow moister to get between the primer and the metal, a common cause for some finishes to lift and crack.

Hi!
Great thread!
Powder coat calipers, is it possible, i mean due to temp? And how to avoid "Faraday Area's"? Higher or lower amp?
Anything special to think about when doing suspension springs?

[APachon71RN]

How low can you go on your baking temps for powder coating? I've read that when powder coating aluminum wheels that you want to find a powder-coater who can do a <250deg bake to prevent metallurgical damage.

BYRNE... this seems a good application for cooling fans. You mentioned much earlier in thread that PCing would be better choice for fans because there are more color choices. Do you have a color chart for Ceracote that can be referenced? (Pardon if you already answered this... I did skip ahead.)

[911pcars]

Cerakote is highly rated.

That said, Eastwood has recently announced a product called Exo-Armour Coating:

According to claims, it's a two-part, high temp, corrosion-resistant, low gloss, air dry coating to protect painted, bare and polished surfaces. In addition, it can be applied by brush, pad or spray. No affiliation and no independent reviews I could find.

Exo-Armour High Temperature Clear Coat

Anyone?

Wow, I love the inside color of that wheel. Is it possible to do an RSR type finish entirely with powdercoat or is the masking required too complex?

[JOHN21BLACK]

So your saying you prefer powder over ceramic coating on headers. Thats hard to believe. I have had heat exchangers powder coated and burn and chip right off header pipes. I dont think it can handle temps up to 1300 deg.F. I am taking a set of early SSI style heat exchangers to have ceramic coated today. Inside and out 3mm thickness silver color.

I used Christian for my exhaust. He applied Cerokote ceramic coating and they look absolutely beautiful!! Great work and reliable. I am taking a bunch of suspension parts to him to have blasted next..

Thanks
