It's not often that Neville and I disagree, however,,,,,,,,,,,,, on the odd
occasion we diverge slightly
Colloidal silica, (Cabosil) allows more Expancell to be added without loss
of spreadability, or if you prefer, better spreadability with the same
ratio of resin/expancell. Try this Neville, mix up some resin and filler,
now mix in a spoonful of Cabosil, tell me (privately {:-) if it spreads
easier?
I don't see the point of 1/4 inch thick filler, except to be sure there are
no areas that are too thin. I use 1 1/2 or 2mm strimmer line as a thickness
gauge. After half an hour over again with the spreader to fill in the tram
lines without adding any more filler.
Obviously you can't use this method on steep curves, then I use a serrated
scraper for the first fill, then smooth ove after it settles a bit.
I'm not as young or strong as Neville is so I tend to avoid hard work.
After an overnight cure I then trim off the excess with a small, very sharp
wood plane, (thanks to Kingsly Hurst for passing on that idea). It gets rid
of the outer skin which clogs the paper unless you wait three days. I hope
this helps understanding a little more?
