Once its dry - sand down with 80 / 150grit - till you get the desired shape - DO NOT oversand - and damage CF... Better just sand down all the roughness - and clean everything really really good - use some pressured air - to get all the dusts out of the CF.Lay down another layer of Resin, let ir dry - and sand it with 150-220grit. Once again - if still not flat / nice surface - use some soft brush and lay down another thin layer of resin And finish everything off with 800 wet grit. After this - layer or 2 of clear coat
As for the parts being to big - just TEST them out after first 2 layers of resin. once you sand down first time - just go and test them. And you will see all the places where they need to be timed / sanded...
To be honest - if you never did anything like this - it will be hard enouth to do such parts as interior for the first time... |
Thanks Doggy, but I didnt want to get into details too much. I was gettign ready for work and I was on my phone.
On a big surface the CF is layered straight after the first layer so it gives you room to play, but yes, on a small part like this, let the first layer to dry till it gets tacky but not sticking to your hands.
Make sure you use the right resin/epoxy and hardner ratio as well. I think on a 5:1 you need to leave it about 2-4 hours to get tacky. Have a separate test area so you dont touch the part to check whether is dry or not.
I think too many layers of resin could make the part look too big but each to their own. On the other hand, sanding down the part to an even surface is more important I reckon, and that also depends on the grit you're using. But yeah, 3 coats, sand down, and than clear coats should do the trick just fine.
