Hi all, im trying to make some exhaust protectors from carbon. i now made 20 of each and only 5 of them are good enough to use. The problem i run into is that all the flat area's are fine but 2 spots where 2 bumps are, always fail.
Here is the mold, polished and working like a charm.
This is how every part comes out shiney but always bad on the bumps.
So this is what it looks like every time around the bumps/holes:
After this i tried it with some rubber gromets around the holes to maybe push the fabric down more but still there. I also tried a fast infusion and a slow infusion but same result.
But still this as result:
Does anyone have an idea what i do wrong or can do diffrent? its costing me too much now. I always let the resin sit for 10 mins after mixing. full vac no leaks.
these did work:
