Clear coat varnish application to the engine...
Good morning..
 Recently a Porsche 911/964 had its engine/transmission dismounted and lowered, the two elements were split and a new Porsche clutch kit was installed. Taking advantage of the engine’s easy to get accessibility and at the same time having the total accessibility to the engine-less engine bay, my question is the following: Would you, as air-cooled engine Porschists completely spray: TRANSPARENT PLASTIC/ ACRYLIC, FAST DRYING, CLEAR COAT VARNISH THAT IS WATER RESISTANT, GAS RESISTANT, EVEN DETERGENT RESISTANT TO THE ENTIRE ENGINE INCLUDING EVERY HARD PLASTIC, EVERY FACTORY PAINTED PART, EVERY HOSE, EVERY CABLE, EVERY NUT AND BOLT, THROTTLE LINKAGE, THE SOUND INSULATION, EVERY THING THAT CAN BE SPRAYED AND FOR GOOD ORDER'S SAKE, THEN DO THE SAME APPLICATION OF CLEAR COAT VARNISH IN THE ENTIRE ENGINE BAY, INCLUDING THE ORIGINAL ENGINE BAY PAINTWORK, OIL HOSES, ELECTRICAL CABLES, ETC.? What are the pros and cons, rights and wrongs? Has anyone ever done this before, if so I sure would love to see the results. And, if someone has done this, how did they get the clear coat varnish off? This is my engine today (?), what would you do? Would you do allow this treatment to your engine, or would you remain "Original spec" with it's natural "as-it-used-to-be" look? Thanks for your help once again. All my best, Marc964.

I would never do anything like that. That varnish is eventually going to flake off and get in everything.

Or it will turn a nasty brown color from the heat, and then look like crap.

I did something like that to my fully assembled 2.2L S long block about 12 years ago, prior to final re-assembly of the complete engine. Same to outer cases of the 911 transaxle. The car has only been driven about 2500 miles in that time, but it has held up well. My intent was to prevent Mg O2, and it seems to be working...
 >I agree, would not spray the entire complete assembly, sure to be sad in the long run..

++++1001 with Kurt and 3.2.
Unless you never move the car like silver, do not do it! I've fought that flaking, brown crap on all sorts of customer cars back in my mochaniking days and our Range Rover still has it all over the plastic (which there is quite a bit of) from the PO. Don't do it. The stuff should be banned. Prob. harmful to the environment. Sorry for the rant... |
