- This is a 1986 Corvette I’m working on for my dad. The previous owners had some bodywork done to the car and the wrong materials were used. Chevrolet started utilizing SMC body panels on the Corvettes in the early 70s and by the 80s the cars were pretty much all SMC panels. When doing repairs SMC compatible materials need to be used. Otherwise any bodywork done may eventually peel off like this did.
Exactly , SMC and fiberglass materials won't work with each other . The SMC materials are harder to find .
Very important to do your research...i used a Lord Fusor product that was made for smc and it didn't stick any better than the regular fiberglass resin did 😂 very expensive proposition because i had to purchase a special applicator gun. I now only use Vette Bond by Evercoat ....$85/qt but worth the results...it sands very well and feathers nicely into the surrounding substrate, it is engineered to sand at the same rate as the original smc which is a great feature and it won't show the original damage which is called ghosting or mapping, some body fillers will show a hint of the original crack or hole once the sun hits it..for small repairs you can use "panel adhesive", JB Weld now offers a two part product its only a couple ounces and sells for $7 or so
Nice tip. Thank you.
@@littletincans good on you for addressing this issue. Some guy made a video using the flexible bumper repair two part product which is just wrong 🤪 I customized my '85 by shaving the door handles, mirrors, side marker lights and emblems and grafted on a fiberglass rear bumper cover so I've had my share of failures working with this material...gets expensive 🤪 it's nice to save other owners the trouble and the expense of the trial and error method
Thanks for the info, good to know. Just subbed keep it up.
they switched to smc in 1973
Yes. Certain panels started being produced with the SMC method clear back to what I believe is 68?. Is 73 the first year that they came all SMC? I know there were a few rough panels on my 72 indicating that they were not SMC.
I found it interesting, but I can’t, for the life of me, figure out why he would peel the delaminated fibreglass resin repair off and throw it onto the roof of the Corvette instead of on the ground.
Because I didn’t want to pick it up off of the ground. The whole car needs to be repainted. Not just that section. It didn’t hurt the paint on the roof.
But I could see why you would think that. And if that was the only problem area of paint I obviously would not have done that.
I have an '84, but I've put on a true fiberglass '96 update kit and I'm getting ready to prep the body as soon as I complete the FiTech fuel injection. I also have the '96 rear flares which just adhere, do you know if there is a special adhesive to go with the SMC or can I use the 3M Structural Adhesive (08101) I'd planned on?
I would definitely research what to use on that. I believe that the two-part bonding adhesive would work sufficiently. I would want to make sure that your materials will work with both SMC and standard fiberglass.
@@littletincans Thanks, I will have to review this and contact 3M. I was not aware of the SMC material by GM. I initially reviewed it just for its adhesive quality.
