Clear coat coming off brake caliper paint




Make sure that your brakes are COOL before you put that high pressure water on them....if they are hot then the thermal shock can cause the paint/clear coat(which is VERY thin with VERY little mass) to contract much faster than the caliper itself(which is VERY thick with LOTS of mass)...I have seen this cause cracking on many many many occasions.....in my opinion there should be no clear coat at all on the calipers for this very reason...a good application of a high temp base with elastomers in the paint should give great looks and performance for the life of the part

One a side note, I have noticed this, and take a warning ... the underlying red WILL COME OFF when you wash your car. My rags turn red when cleaning them with just water, and the are "sitting overnight cold".
Notice the clear coat almost completely gone.
Soft bristle wheel brush with dawn soap to get rid of grease and brake dust.
I waited about an hour to let it dry in the the sun.
While I was at it, I might as well clean up the inner part of the rotor so I used sand paper & steel wool to remove the rust.
Used Brakleen to clean the residue.
Mask away ...
VHT paint high temp paint.
I used 1 light coat to start off then 3 heavier coats after. I let it dry about 15 to 20 minutes between each coat.
Back to the calipers. I used model paint to touch up some small nicks. Let it dry for about 10 minutes.
Better than before.
Dupli-color High temp gloss clear. I did 1 light coat and then 4 heavier coats letting it dry for 15 to 20 minutes between each coat.
Finished product....
Its been about 4 months and they look perfect. I do use an electric pressure washer from a safe distance but I don't see any signs of wearing.
