Its time to work on the FG rockers for the ABM.

The PO modified the rockers to fit the steel flares, but the rockers are rough. He suggested doing a thin finish layer of body filler to smooth out the rockers.

Is this the right call?

if it will be thicker than 1/4 inch i would use bondo with kitty hair or fiberglass resin with kitty hair to stop it from cracking.

Got your VM but had a busy weekend and failed to call. Post some good photos and we can talk.

Fiberglass strands. Or add micro-balloons with the resin to make a slurry.

The front side doesn't look that bad, I would suggest using a product by Evercoat called Everglass. It has short strands of fiberglass in it for strength and it bonds well to a roughed up fiberglass surface. I would skim coat the entire piece and on the flat areas hand sand with a Dura-Block backing pad. Dura-Block also makes a round backing pad for the curved areas. You can find most of these items at any good automotive paint supply company. Having the right tool can make all the difference.

+1 for durablock. eBay has a kit for around 50 bucks

Those look a lot like a pair I got that were manufactured by AA. The quality and fit was so poor I had to heavily modify them to get them to fit requiring much tuning and cutting. I have one side done to acceptable quality. Only issue is all the Bondo and fiberglass cloth it took to make them straight and fit properly added a lot of unwanted weight. I am tempted to use them as a plug and have a set of carbon parts made.

I do know they were patterned after the real 914-6 GT set with correct flared ends. Many of the replica aftermarket GT rockers don't have the correct flared ends. Either too stiff or incorrect radius. The factory fit and finish was not the best on the GT cars as they were probably rushed to make the parts from the few cars I have seen.

If I ever get seriously motivated I would like to build a set in CAD and have them CNC milled to make the master molds. This would be the best method by far. but also the most costly.

I would use kitty hair and gel resin. Mix the two to make the kitty hair flow better. Feather it out and sand smooth. Use bondo or filler putty to make it perfect.

Screw kitty hair. Unicorn hair is way better

I am at this stage too. I got mine from AA and one is twisted. Thought about using steel rockers and bonding flared ends on an filling with kitty hair and Bondo.

Oooh. That's not a bad idea actually. It's not like there's a lot of structural integrity needed at that point. Interesting...I may steal that idea.
