Hi all,
I was hoping for a little help from this wonderful community on a problem I've been running into. I've looked through a bunch of old threads, but nobody seems to have had the issue I'm having. Any help would be much appreciated.
I'm using Rondo in place of fiberglass. I've tried this on foam (using docholiday's method of sealing with PVA glue then 1:1 rondo mixture over top) and on cardstock (sealing with straight resin first), but the problem is always the same: my Rondo cures with huge drips and brush marks and uneven spots. Normally this wouldn't be a problem, right? Except that for some reason my mixture is IMPOSSIBLE to sand. I worked for hours with the grittiest sandpaper and the imperfections weren't going anywhere. On my next project, I went to town with an oscillating tool, which roughed out the drips, but the end product was far from smooth.
All the Rondo posts I see on here are of perfectly sanded, perfectly smooth pieces, and my stuff isn't even in the same ballpark. Is it a problem with my Rondo? Is there some magical sanding technique I don't know about?
My next project is a Dredd helmet, and I want it to be as perfect as I can get it (open to either foam or paper). Should I even bother with Rondo or is fiberglassing really the only way to go? Thanks in advance, I've already learned a ton from everyone here.
