Building a Buick LeSabre T-Type Spoiler

 A donor factory LeSabre T-Type spoiler and trunk lid are being used to recreate the rear spoiler. The donor spoiler was warped, rusted and had to be repaired and straightened before it could be used to make the mold for casting new, correct spoilers. The owner of the company building the mold and making the spoilers did all of the repair and molding work. He decided he would make a three part mold that could be used to cast the spoilers using fiberglass or for injection molding using other materials. He also had to build a jig for correct placement of the mounting bar and studs.

First Reproduced Spoiler

The spoiler reproduces all the the curves, key lock outline and under spoiler lines exactly and the top is straight and smooth. The original spoiler weighs just under eleven and one half pounds; the fiberglass unit weighs a little over five pounds. It looks like some trunk lid re-tensioning may be in order. Not the best pictures but here is the black reproduction spoiler next to a stock, slightly beat up white one:

Repairing a Factory Rear Spoiler

The factory spoiler swells and warps because the metal mounting bar that is encased in the spoiler rusts, expands and causes the damage. Just as the donor spoiler had to be repaired to cast new ones, Greg (BuickNEWF from www.lesabret.com) repaired his factory spoiler. Greg replaced the mounting bar and studs with one custom fabricated of stainless steel. Be sure to visit his website pages and see and read about the repair work he did on the rear spoiler and all of the awesome work he is doing to his 1986 LeSabre Limited coupe. http://www.cardomain.com/ride/2494425/1
