Let me know how that works Woodchuck. I have an old iron head I was thinking of trying that on.

 

I started using Cycle Care engine brightener. When I did the engine build it put it on and the fins look new 4 years later and I don't have to use it as much as the other products.

 

Been using the S100 but may give Pig Spit a try and compare. Still have to shine the chrome after use because that stuff sprays over everything. They also claim that their product gets better with engine heat. I'm not sure about that though.

 

I used stove black where the crinkle black finish had peeled off parts of the engine on my '89 EVO engine. The color and sheen were a good match. It was more durable than the original coating. Any stove black that I got on the fin edges when I did the cylinders easily sanded off after it dried. It went on easy (no drips or streaks) and adhered well even to the surfaces that didn't get that hot.

 

Just notice my S100 can last night was 4-1/2 ounces and I paid $10 for it. Pig **** is 10 ounces and $12. Much better deal, wondering if it does as good a job as S100.

 

Only 1 way to find out

 

S-100 as stated above

If you polish the edges, you will remove the coating and it will oxide or turn white frequently. Unless it is really bad, I would not polish the edges as once you do you will do it every week.

BTW - I did on my '81 many years ago and found
Haapich SemiChrome works great. Stuff is expensive so keep polish rag until it so old and crusty before throwing away then rotate the last buffing rag to polish.

+5 on the S100 engine brightener... GREAT stuff!

 

Not sure on the mentioned fixes for the black finish on the engine, but you could always consider putting the diamond cut finish on the heads. They look great and it will help with the cooling too. My brother had it done on his '03 and it is sharp looking. I think the website is diamond headz.
