yes the west system is good. and made here in bay city mich. a bit over kill.i have a friend that builds air planes with it. but a thin coat of filler will do the job sanding is not bad if you put it on smoooth this is the way i did air plane cowls and fared out the plane parts but if you want to spend the money you could use the west system and use the saran brown powder with it.it sand very good
