Quick question:....

MY calipers are powdercoated RED.... what & where is my question..

What is used to strip powdercoating?... someone told me BEAD blasting..... and that sand blasting is not recommended.. is this true?

Where..... Does anyone know someone that does TOP notch work that will strip them for me?... can I have the contact information?


Thanks for your time

Smitty

 

Sandblast. Any paint shop. How else?

WHY?

 

Smity I might have the answer to your problem.... give me a ring

 

how about u trade me your stock red calipers for mine?

 

I would not sand blast, there are many different ways ie, its like sand blasting ( SPONGE BLASTING)Bbut its little pieces of foam instead of sand, pretty expensive, but thats what i would do. If you need some more info pm me,

or bead blasting then just repowder coat

Where is Dave when you need him?

 

i heard paint thinner does it , but not sure....

 

y u want the red off??

 

"""After removal, strip all elastomeric parts (rubber, plastic, etc), and soak in MEK, Methyl Ethyl Keytone, for about a week. After 24 hours or so, there should be reasonable loosening of the powder coating. A week should float it all off. MEK is a fast evaporator, so cover your soaking bucket. WARNING! very flammable!

Alternate method: Propane torch, or MAPP gass. This does a good job also. Just don't go overboard. Just burn the paint off. Remeber, these are your brakes! We don't want to heat these things so hot that the heat treatment is effected.

A third method is to get them sand blasted, but do not damage the piston cylinder bores. You would need a special masking tape.

If it were me, I would remove ALL components (i.e, even down to the brake bleeder nipple), do the solvent soak for a week (we need to get rid of ALL grease and oil), then do your sanding to make them pretty.""""


So FYI for you future reference..... I got my answers..thanks all..

P.S. yes Darrin, the red just stands out way too much.. I want GLOSS black and the name ROTORA off my brakes... those morons don't deserve any advertising from me...

 

i feel ya, keep that bitch in the garage all winter mang

 

go to your local autobody supply shop and get some aircraft stripper. this stuff will eat through powder coating in a few minutes. just brush it on, let it bubble up, and the coating will start to fall off. make sure you read all the directions and warnings, this stuff is no joke.

no need to soak it for a week, lol.

 

I heard that aircraft crap works excellent, but it needs to be like 70 or warmer for it to work.. I could be wrong though.

 

Dave here: I'll be doing Smitty's calipers when he gets them to me. He wants them to look EXCELLENT, and they will. I am sure Smitty will host pics when he gets them back.

Lucky for Smitty, I have just spent the last 3 YEARS of my life learning how to powder coat castings for my company, so I got lotsa practice!

As these are sand castings, they come out of the mold kind of rough, and Smitty says he will spend an extra hour or two smoothing them out, and it will make a huge difference, you'll see!

An interesting aside, painting castings is very different from painting sheet metal, because castings can and will "out gas" (don't worry Smitty, I got it covered.) Out gassing means when the casting is heated, gasses trapped inside the casting expand and try to break through the surface.

The answer to this is to preheat the castings to 400 F before applying the paint. Apply the powder coating after that.

Here's the interesting part: In trying to understand out gassing, I visited a foundry in Northern Ohio two years ago to observe the process. THERE IS NOT ENOUGH MONEY IN THE WORLD TO GET ME TO WORK IN A FOUNDRY! Dangerous as all hell! While me and the boss were standing there, we were constantly being bombarded with little metal particles, and we could never figure out from where they came from!

Maybe 80 to 100 people worked there, and the plant manager told me, tounge in cheek, that he spends $50,000 A MONTH for safety equipment for the workers. Six month later, the place burned down to the ground.
