What did youi do to prep them? Did you suff them with say a scotch bright pad or did u sand blast them or did you do nothing at all to prep them?

Thanks

 

are you trying to do them yourself? i know when i did my valve cover i just sanded out any imperfections i didnt think they would take care well enough. in all honesty your powdercoater should be prepping them.

 

The company where i am getting them powder coated does'nt do prepping. Its only gonning to cost me $46can to do front brembos and rear calipers with the brackets

Do they even need prepping bessides cleaned realy well?

 

I heard that'll melt certain things in the caliper.

 

You have to completely disassemble the calipers

 

I take it you are going to Piranha....

Just sand them to the finish you want (remove any casting or machining marks you don't want visible later), and give them a good prep wash with surface cleaner (camp fuel works too).
Piranha will give them another pre-clean, and tack wipe before coating them to avoid contaminants.


Edit:
Remove any decals and paint already on the calipers too. Paint stipper will do the trick.

 

Yes indeed piranha is where im taking them. I will give them to my buddy at the body shop here at ulmers where i work and tell him to prep them free of charge.

 

any part to be powder coated should be blasted to remove any of the old coating. wven if it is chemicaly stripped a light blasting will insure proper adhesion of the powder to the part. The only time this would not be done if spraying powder coat over pollished alum or chrome. chrome and polished alum under powder will work but the link of the coating will not be good. flaking chipping will result I have seen it come off of chome in sheets. I find it odd that any powdercoating place will not prep parts with blasting as its just not correct no mater what chem etching is used. Just like in automotive paint its all in the prep. you can paint right over a good factory paint job with out sanding and it will look good on the short term but longer term is junk.
any further questions feel free to hit me up

reckless racing powder coating

 

Note that where we live, 90% of all industrial processes (including powder coating) are not used for the same purpose you would use them for..... We're in the middle of the oil field.

Any process done out here either; is done prep done in house, done by a specialized shop, or is completely disregarded due to machine turn over rate (usually annual).
Furthermore, the amount of local places specializing in sand blasting and surface restoration is phenomenal. For an already busy place, specializing in 'just' powder coating, it's not economically viable for them to venture into another market, such as surface prep.

.... cliff notes; it's just the area Sheldon and I live in.

 

usually metal products are blasted down to remove all of the old coating. then you need to sand out and imperfections and give it to them. they will whipe it and put something to prevent corrosion.

 

your correct when talking about ind kinda things but when it comes to custom coating what it looks like matters just as much as if its coated or not. to me if your going to do a half ass job powder coating it might as well paint it. ( in reguards to car and bike parts. )

What are the guys that get their brakes powder coated doing about the brembo logos?

 

Replacement decals.... you can find them on e-bay.

 

Did anyone replace their piston seals.?
