fairing compounds

[PressureDrop]

could you guys who have rebuilt and painted answer 2 questions for me...

1. exactly what compound did you use for fairing, (ie. brand names and speifics)

2. also what filler did you use for filling unwanted screw holes and suchs,

please be specific, thanks!

Ben-

For the areas where I am using polyester I am using LBI Fiberglass brand "Fair so Light". I am very pleased with it thus far. I would compare it to an auto body filler that is a bit easier to sand.

For the areas where epoxy was used I am using microballoons also from LBI fiberglass. For all of the screw holes I have been grinding them out and filling with sturated mat and then the appropriate filler.

For fairing I have been using a Porter Cable 6 inch variable DA and various air tools. I also plan to use a 3 foot long board for the sides of the hull.

Awl Grip also makes a good fairing 2 part compound though if I remember correctly it was a bit pricey,but it good stuff.

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!!
