BEFORE #50


Started cleaning the engine today. This is gonna be a very unpleasant, difficult job and I'm not looking forward to it one bit. But, it's gotta be done!

Any tips on what to use? Mine's in the frame and isn't coming out so I know it'll be fiddly and time consuming anyway. - John

Hi John,
Get ready for some sore fingers! First of all, remove any removable panels and decide and either send them to your local metal-polishing shop (recommended) or buy yourself a polishing-kit and do it yourself. If you've got lots of patience, time and determination, you'll get a great finish, but personally, I think it's better to give the job to someone who does it for a living, while you utilise the time to prepare the rest of the engine.

I paint my engines with MANY thin coats of Sperex Very High Temperature silver paint. It's extremely simple, but you have to resist spraying on too much at one time. Lots of thin coats, lots of drying times and repeat the process.

Needless to say, prior to painting, you MUST clean the surface and for this I always use Scotch-Brite pads and stainless-steel wire brushes AFTER giving the engine a thorough degreasing.

Whatever method you use, be DOUBLY SURE to clean off any remnants of abrasive material THOROUGHLY and be sure not to allow any of it to fall into orifices which lead to the inside of the engine and/or oilways.

Tom.

Sorry, forgot to say, use lots of old newspapers and do a good job of masking off surrounding areas such as the frame, etc.
