Good afternoon,
The engine heat definitely will not take away the shine from our custom polishing services although we do offer a coating service as well at the customers request. It really depends on the situation to warrant getting the parts coated as I will explain in a little more detail below.
If the part that is being polished gets dirty all of the time, wet all of the time, not cleaned very much, etc then we would recommend going with our coating service on the part after the custom polishing.
However; I do not like selling customers something they do not need, so in Naders particular case he will not need the coating services as he keeps everything very clean all of the time. Again, engine heat will not be an issue at all...the shine will still remain.
Thanks
Tony Brock
