fairing compounds

[Scott]

Hi Ben

I've been using the WEST System epoxy and the fillers # 406 which is a colloidal silica (cabosil) and a lighter weight one # 407 I think..

406 is tough to sand ...but in my eyes that means its tougher material.... and the 407 Is a breeze to sand. I'll use the 406 to fill small nicks and screw holes sometimes adding glass if the hole is larger than a dime. The 407 I'll use to fair work that has been filled primarily with the other mixture, minor nicks etc....Its a easily sandible fairing compound. but I feel less durable than the other mentioned...Like Trayder says clean it up with a grinder/dremel tool to get a clean bonding surface....keep things clean with acetone. I have a Makita 9227 sander/polisher with a 7" sanding disc on it ....60 grit and look out ... this combo cuts so well you've got to be careful you dont make more work for yourself [img]images/icons/grin.gif[/img]

I’m also trying vinylester resin for laminating the hatches…..and using a similar pre-mixed fairing/bedding compound from LBI. Think its called Bondalite…..I think it’s a combo of Resin/cabosil/chopped glass…..intended for this kind of laminating .. I just hope it works!!
