you realize CHROME does not REDUCE heat...in fact it makes things HOTTER
(and i dont mean from a reflective perspective)...chrome tends to
trap heat IN.
that said its been years but i have used browns plating (in kentucky)
many many times for chrome and gold plating of motorcycle parts...
top notch and very well known !
you MIGHT consider powder coating...the coating holds up better
and can look as good or better than paint or chrome...and you can
PICK your color (including chrome)...its typically CHEAPER to apply
TOO.
eastwoods has DIY kits (can use the wifes oven to cure "large" parts).
