The last engine I had with the coating never flaked off...It worked well, so I just got a brand new can of it from Eastwood.

As far as hiding the accumulator, I had a 2quart one hidden under the radiator...Literally underneath it.....But I have a new rad, and this one required an external trans cooler, and the hoses run thru there now, so I doubt it will fit there...
