So first time with wheel pants. Do you put silk span on them as well?

You relative novices need some advice from a guy who's been there.  If you put silkspan on your pants, take them off before applying dope, particularly thin dope which could run into the inside.  Similarly, take them off before ironing on MonoKote, particularly on the crotch area.

Hope this helps.

So maybe use fiberglass and z-poxy?

Nothing wrong with polyspan, been there done it!  Do half at a time with the seam running for and aft.  Not as hard as you think, give it a try.

Not to contradict my friend Howard, but you may want to apply .50 oz glass cloth to toughen them up a little to better handle the wear & tear they may get.  And most certainly take uncle Howard's' astute recommendations, by all means. 

I tried glass, but it's itchy.

Silkspan, Silk, or 1/2 oz. fiberglass cloth applied with Zap Z-poxy.  I like the FG best of all, much more durable.
