Actually the glow brush may give you the same effect for the outer edge. Try using a flat brush and then using glow over it with a lighter shade of the same color.
If not you can try creating the brush effect in making custom brushes. When it comes to digital effects, painter is not the best program to use as photoshop would be. BUT it is a very powerful painting program. I've been using it since 2006 and I use it a lot still. ^^
im sorry i dont know corel painting that good but looking at the image i whuld say its just a lose brush of yellow and then a watter brush whit white in the middle and then using pressure to get the effect or just a smudghe tool for the bend
