Flow coat advice please

[DaveP]

All,

First foray into a kit build starts next week or so. I will have questions I'm sure

First one is with regard to flow coat. I'm doing the underside of the bonnet of a Kobra. I assume it would be good practice to do under the rear clam?

Bonnet gets painted in body colour I assume though.

Any tips on the amount of flow coat I need. Best makes and where I can purchase them and method of application ( rush or roller?). How many coats?

As background I am intending to go a dark silver body. The donor is black so I a, planning black or grey flow coat.

Any help is appreciated

Dave
