I bought a set of fiberglass rocker covers, black, glossy - perfect.

One of the last things to go on the car - I tried to resurrect the originals but they were too far gone, sand and grind and there was nothing left!

I go to put them on and the top part that is supposed to sit on the bottom of the door frame was too short - did not cover the holes to mount them. Took a closer look and the lip on the top of these covers was curled.


Spent the night trying to straighten them.

Buyer beware - some assembly required! 20 minute job has taken 4 hours. Still not done!

I feel your pain! Well, actually, no. I was so disappointed with the fit that I sold the fiberglass rockers I bought. OK for a track car, not OK for a street car.

Please post the "after" pics. I'd be interested in how yours turn out.

Best of luck!

HA!

Perhaps I bought these from you? I picked them up on Ebay.

Either way, will close out this thread as we move along.

Don't heat ,you will weaken the resin and make stress cracks,you will need to make relieving cuts with a 1mm cutoff wheel and fit some sort of strong back out of wood or metal etc,you may need to grind the area so its thinner and it will bend outwards better,when you are setup and clamped that edge out,glass up the area of cuts and ground back areas,just make sure you tape over the edge so the strong back isn't stuck to the part .
Let it cure for as long as you can otherwise it will tend to move back part of the way from the original molded shape.
Fiberglass parts never seem to fit because most don't like the tooling cost to get a perfect correct pattern (plug) and the mold which is the final shape won't produce the correct fitting part.
My front valance/spoiler is fiberglass and is a really crappy,after working in this sticky shit for years I'am amazed @ the lack of QC and bad layup procedure used,the problem is compounded by cheap labour used and folks that aren't proper laminators or mold makers for that matter.
Good luck.

Just out of củiosity who was the manufacturer?

I purchased from a private party in Ebay. Not sure who made them - they were inexpensive - Buyer Beware!

Well we will have the Sheridan molds soon so I look forward to seeing how they are.

I was able to calibrate the angle to perhaps 1 radian using these super-precise instruments.

Almost done mounting.


Is the bottom of this thing anchored or is it just flapping in the breeze?

HELP!

Sheet metal screws into the long.
That is what I have seen.

Even with the 'lip' of the rocker covers 'straightened' there is not enough meat to screw through!

Time to get the lip stretcher. A little feathering of Epoxy.


Only need 1/2 an inch!

That seems about right

Slather on the Epoxy - Liquid Weld

Now, I can dremmel that into shape!

5 hours into this, not even 1/2 way done!

I can get within one radian just by eyeballing it. I'm that good.

fiberglass parts never fit correctly unless by some miracle

I agree George,


Or they could have the lip cast a bit longer! (wider?)

Will post as progress is made.

Project going well - the JB weld holds, is solid and perhaps stronger than the straightened glass which bent pretty easy with heat and then with my expert calibration equipment (see above) stayed at the required angle.

More progress today.

Why epoxy may I ask ?,these moldings are made with polyester resin,with what you are attempting to do you may have issues.
Good luck on this one.

JB weld was used, seems to be a very strong bond - the stuff is strong as steel.

Working with these moldings I would say it is much harder than a resin, however, I will defer to the manufacturer......whom I cannot find.

Thank you for the note,
