I have been running I/C Engines for 30 years now and have never had any trouble using those compounds when needed.
The Stuff is good enough for real car engines so why not model ones..??

I am not having a go by the way...just speaking from my own modelling experiences using the stuff I mentioned....It works for me....and I haven't trashed any engines yet !!
