Hi guys,

I've seen some marks appareing on my frame and engine.

I would like to remove them. On my frame i could find a product that did a great result as you can see here, i did apply the product on the surface and with a tissue it made the work. Put on my engine it doesn't do it really much.

I did see a lot of people here talking about scotch brite green red and so on with simple stuff but it actually scretch the frame (see the picture below), also polishing will remove appart the coating and you'll have to do it all the time. Also i don't like the shiny look when you polish a frame. i would like to keep it look more stock.

I would be more concerned about the way your plastic is cutting into the frame.

A lot of CRF have this issue when they getting a lot of hours, i didn't know about this, the good thing to do is to put some ruber or velcro under it when you get the bike it will elevate the plastics. and protect the frame. 

Thanks for noticing

WD-40, red scotchbrite pad and some elbow grease. Be mindful of what chemicals you're using to clean moving forward.

Is red scotch brite much different from green.

I dont like the fact that it screth the aluminium but also destroy the coating protection.

It looks like it was environmental to me. It happened to me by letting it set on the bike after a winter ride.

Yes it it. The color indicates the abrasive property.
