What are the perks to gumpaste over fondant?

I have never used gumpaste, hard to get hold of in Scotland but i've bought some Tylose and heard i can put some into fondant and i will have gumpaste? Correct?

I'm doing a motorbike cake and the details is quite fiddly and read that maybe gumpaste would be better used than fondant?

Hi, gumpaste is used for making flowers. But you can use 50/50 gumpaste and fondant and used that to make figures and other accents. Also you can mix some tylose to fondant and use that to making flowers and figurines. But for flower making gumpaste is really good.

Mixing tylose into fondant works very well for small figurines as well, like the details on the bike you are planning to do. You wouldn't want to make the entire cake be a bike, and cover that with gumpaste, but detailwork, or figurines that can be removed before eating are perfect for this sort of thing.
