If you take a look at the last picture I posted on my bike build you will see a mould done using the uni mould system, ive polished the in part piece and left the outside as was, you can see the difference between the two parts is quite pronounced and was done in half an hour with the drill and foam mop, very easy to do and well worth it.

Thanks gents...looks like I will be spending some time on minor repairs.

I will use the chisel, gel coat, and tape method illustrated in the "How to carbon bonnet" easycomposites video.

Repair it mate, like Warren says its cut out, fill,sand then polish.

You will regret it as the marks will be in the part and its a real ball to work after.

I went to my local paint supplies and got a Velcro foam polishing kit that fits a rechargeable hand drill, they are cheap and very easy to use, add to that a medium compound polish and you will be amazed how good you can get the mould to look.

That will repair no problem. Once the repair is filled, its just a case of flatting back then polishing to a gloss to match the rest.

Yes, it's a little flexy from corner to corner, but not so much that it will be an issue.

I think I'm just going to go ahead and infuse one roof without repairing the mold....I can sand/paint the final product. I'm suggesting this because I've never repaired a mold and I'm scared I'll mess something up before I pull a part.

That looks excellent, congrats and well done.

Is the mold a little flexy for your liking now that the roof is off or are you happy with it?

Let's see some infusions.....you're going at this very well in terms of time I might add.

The mold is done and the OEM roof pulled cleanly with surprisingly no drama.

A couple very small areas of alligatoring but otherwise in really happy with the mold:

I think it might be useful to put reinforcements also horizontal and diagonal to prevent flex as you wrote

Finally done with the mold. I have about 6 layers of chop strand mat and 1-2 layers of heavy weight canvas. There is a little "flex" in the mold still...for example, I can lift up gently on one corner and the opposite corner wI'll stay in place. I'm hoping this will minimize when the final layers of CSM cure.
