I don't have much experience with fiberglass and this is the first time I have tried to create something with tight corners and contours.

I'm fabricating a console and other hardware for my car.   I tried glassing the insert that goes around my steering colum first and I can't get a clean edge where the glass makes a 90 degree bend.  No matter what I try it will lift at the edge and if I try glassing anything beyond 90 degrees or upside down it will not hold.

I've tried 8.5 oz twill cloth and 3/4 oz mat with no success.  I'm using US composites products and I have tried their 635 thin epoxy and  the B-440 polester resin and had about the same results with each.  The polyester resin seemed to hold slightly better but not well enough.

What am I missing here?  I have a lot of work in my console mold and don't want to mess it up. I posted a couple of pics and was hopeing you guys could give me ideas on how I should approach glassing the console to get nice clean edges and corners where the gauges will go.

I guess it's just foggy what you're trying to do. If you're trying to adhere to something while creating an angle have you tried "kitty hair" (resin and glass shreds in one product)?

I'll tell the forums one of my secrets for glassing on vertical surfaces and aggressive angles.......... tin foil !
Lay down as many layers as you want and then spray the last layer with a wax ( Turtle Wax, Mother's, etc ) as a release agent for the tin foil. Use a flat foam roller ( for painting ) and roll the foil onto the surface until it contours to the curves, angles or flats. For larger flat vertical areas, you can use cardboard to support the middle of the flat section and then place something under the cardboard to help suspend and put pressure on the glass.
Allow it to cure and remove the foil afterwards. Make sure that you remove ALL the foil because if you do not and your going to use body filler to smooth out the project, body filler doesn't adhere to foil very well.
Hope this tip helps you guys out and let me know how it goes.
