Walter,,
I hve dabbled with the catalyzed clear for a base.
one issue, it is VERY easy to soak a lot of clear into the wood,, making it heavy
It is cool because it doesnt shrink out..
the next time I try it I am going to do like the old pattern RC days,, spray or brush the clear on,, then wipe it off as thouroughly as I can,, let it cure,, then nib it with 320,, I will probably use CF veil and then spray a very light coat of catalyzed clear on,, just enough to make it sticky,, lay the veil down, let it cure, then spray another coat of clear light and overthinned to stick it down,, then use catalyzed primer on that,, then sand.
the biggest thing I ran into was that if you use to much clear when sticking the veil down( or glass) it will "float" the veil off the surface and make it wavy. hence the light spray out to stick it down..
I would not use glass cloth personally becausae I beleive it is thicker than the veil and would require more clear/primer to fill..
