Vapour blasting paint or not paint

(1/6) > >>

Ken4004:
When I originally stripped my engine down and had it vapour blasted I made the decision not to paint it because the finish was so good.
My reasoning for this was due to the fact that during the vapour blasting  the surface gets bombarded with the particles and hardens the surface , my I tension is to treat it with AC 50 to be on the safe side.

Let me know your thoughts on the subject, worst case scenario the engine will have to come out and get sprayed .

Nurse Julie:
If you are going to use it regularly and depending on where it's stored when not in use, oxidation sets in quite quickly and it looks bloody awful. It's very easy to keep a painted engine clean, just a bucket of hot soapy water, job done.
Use Simoniz SIMVHT31D, it's a perfect match to original.

McCabe-Thiele (Ted):
Aluminium does not resist oxidation very well, even if you do not expose it to the salt on our roads it also reacts with acid rain not helped by the heat cycles of an engine. AC50 probably works to slow down the corrosion but it will dull so TBH I'm with Julie paint it like it was originally - Mr  Honda knew what he was doing.

Ken4004:
Ok thanks I’ll look into a paint job once I have got it running I’ll add the job to the long list all part of the learning curve.Not too bad to strip the engine down once you have done it before .
I found it very interesting especially the gear change mechanism form memory there were about 40 parts to it so too lots of photos while I took it apart.

McCabe-Thiele (Ted):
You can paint it as a complete engine, the problem would be not being able to heat cure the casings, block & head would be fine. There are some engine paints that will become petrol proof without the heating process. My BiL did his engine on a Fireblade with a US sourced block enamel.
