OMG!!! this product is simply AWESOME!! i had a Kyosho .21 engine laying around and i thought i would try the Engine Buff to see how big my engine can be. i soaked all the parts with the appropriate solution and waited overnight for the parts to expand and omg my old .21 motor is now bigger than my HPI K4.6!!! Thank you for a great product unbelievable R/C!!

I used this on my .21, and now its big enough for a dirtbike. Thanks again!

Warning! Follow the directions and precautions! I failed to read the warning about not using this product on body parts! I experienced huge results followed by a tremendous loss of displacement within a day or two! Be Warned!

yup awesome!!!!!!!!!!

Caution - I used this on my 1:1 scale car and ended up in a 180mph crash (luckily I used go fast goop on the chassis for strength!) but it voided my insurance. Now I need to replace my mangled metro with something else! :o(

I can recommend Engine Buff to all electro touringcar owners with a stock Machubi 540 enige. Although tested on nitro-engines, it turned my 540-size electromotor into a giant; sized like Plettenberg Big MAXXim!! Only after the third batterypack the stuff worn out or so, and the motorsize shrinked back to normal 540-size... Remember to buff your motormount also!!

it does work on human body parts

cant stop buffing everything in site. oh ye dont use on electric shaver motors leaves a very close shave where you can almost see bone but otherwise buff away ,better buy it by the case .mgtman

All I can say is dont use your finger to spread it on.

It's crazy, I was only trying to do my hair, now I can't even get through a door - MaxBasher

From the webmaster: Again we do not condone use of this product on body parts. Please use as directed for your own safety. Thanks and enjoy!

AMAZING, i soaked the whole truck in the bath for a week, now it\'s big enough for me to get in and drive, i\'m going to put some on the wifes tit\'s, hope it works.

I put this thing on My motor and DANG! I need to know how to pry it off the chassis? I kinda left it on too long...also Nova rossi cant explain how My case grew! (I wonder why) Taz
