This is unadulterated BS. There are many, many Mazda RX7's and other rotary powered
cars out there with well over 300,000 miles. 500,000 kilometers. I see many 25 year old
first gen RX7's on the freeways of Southern California almost every day. I saw one
this morning.
I have owned six rotary powered cars. A new RX2, an RX4 station wagon, a two rotor Cosmo,
two 2nd gen RX7's and I currently own an RX8. Some with over 300,000 miles. None of them
ever had any problems with apex seals or problems with the chrome plating.
Some Mazda rotary aircraft applications in gyro copters have over 2000 hours with no troubles.
Rotary engines have been used in aircraft since 1973 with stock Mazda chrome plated
rotor housings. Further more chrome plated cylinders were specified in WW II by the US Navy
for all their aircraft engines for salt air corrosion reasons. Chrome plated cylinders
were also widely used in general aviation air cooled cylinders and still are.

IMHO the credibility of this company is zero.

What JBB are purposely omitting here is critical information on the
**** METHOD **** of applying the coatings. This makes all the difference
in the world and the METHOD OF APPLYING the coating is EXTREMELY important.
Alterdyne is a large company in San Diego that makes generator sets of all
sizes and types for civilian and military markets. Alterdyne manufactured 1,2,3 and 4
rotor engines based on Mazda rotor housings and their own all aluminum
end housings. One of the engineers at Alterdyne by the name of Paul Ross
told me many times the only coating method that withstood the test of time was
the detonation coating method. Gen sets run for years.

JBB is not telling us the METHOD of coating. Due to the exceptional reputation
of the detonation coating method one would think they would say so if they
were using the detonation coating method. They are therefore obviously NOT
using the detonation coating method.

Finally JBB claims they are using the same "coating" as Mazda used on the Lemans
4 rotor engine but that is not strictly true if they did not use the same *** METHOD
*** of coating. Here is an excerpt from the Mazda SAE paper on the Lemans engine.
Note that Mazda used the detonation coating method.
BTW JBB is a Canadian company therefore they cannot be sued for product liability
reasons according to Canadian laws as I recall. I am not a lawyer let alone a Canadian.
Good luck getting anything out of them if they ruin your engine.
