- Welcome to my RUclips channel. This channel is the home for all your vintage Mid-Year Corvette content.
I just finished restoring a 1963 Corvette Split Window and I am starting another split window build but this time its a race car build. I will be making videos every Friday. I will be making videos on my 1963 Corvette Split Window, my dad's 1965 Corvette, my race car split window build, my friends 1960 Corvette, and other projects that I find along the way. Let me know what you think about the video. Enjoy!!
If you are interested in an official MYM hat or if you have any questions please send me an email to midyearmitch@gmail.com.
Check out my Instagram for some behind the scenes pics of my builds.

Sit back and enjoy the show!

I never gave either method a second thought. Till now, you opened up my eyes. I guess I've worked with both types, and yes, the hand laid does take some extra grinding to make a good fit. That was an interesting video, thanks for sharing with us. Looking forward to these next builds. Have fun with them.
Interesting video, Mitch! I'm a press mold guy all the way... It seems the money you save w hand laid, gets burned up in the extra time required to install it. Great vid! A+++++
Keep the videos coming!
Hey there Mitch,
Interesting. I didn't know there was that much of a difference.
Agree, don't feel up someone's car. It may annoy them.
Take care,
Dan
Hey Dan thanks for tuning in. Some guys love to grab bonding strips and I don’t know why haha. I don’t want someone touching my car. It’s definitely a respect thing. Take it easy Dan!
A really good video Mitch , very interesting and informative . Do you ever rest ?
The best for the straightest part is using Apoxsee resin with fiberglass mat and a vacuum bag
That’s a good point about the panels being straight and flat. I didn’t include that in the criteria but that should be a consideration as well.
@@MidYearMitch you will find that if you use Apoxsee resin is thicker and harder to wet out but the advantages are it cures 100% unlike polyester, which never cures 100% and you’d never have that cellulite look after years and years in the sunlight that you get with polyester resin the Apoxsee resin is what is in carbon fiber parts and it is amazing the difference and it’s cheaper than using carbon fiber if you use fiberglass, we have made door skins painted black and left in the sun for months and they look at straight is alien from the beginning
Thanks Mitch !
I wanted to add , a very good friend of mine , he's gone now , but he was forever running his hand under the front wheel opening ,looking for the bonding strip I guess , this was in the 80's and early 90's .Ole Max , I miss him.
Pressed is the Best
Wealth of information.
There's a corvette frame company called Roger's Corvette Frame Restoration in Grand Rapids, MI.
I bought quite a few things from Roger including the 65 project that the aci front end is going on.
I purchased my frame from him. He gave me some money off for my old frame.
The change from fiberglass to SMC (sheet molded compound) happened with the introduction of the 1973 model year and have been varying formulas of SMC since, with of course use of carbon fiber on some models. It’s surprising sometimes how many self proclaimed body/paint experts give advise to others to be careful not to sand through the gel coat and into the fiberglass on 73 and newer Corvettes, which of course are neither traditional fiberglass, nor do they have gel coat. Unless of course as you’ve pointed out, they have hand laid aftermarket body panels on them.
Great comment thanks for the information on SMC. I’m not familiar with that type of fiberglass since I work mainly on 63-67 vettes. Absolutely you can grind the whole way through that panel and you won’t find any gel coat haha.
@@MidYearMitch I am pretty sure they started making SMC in 1971. SMC - Sheet Molded Composite
@@TheJagjr4450 you are correct; however, in 1971 only a few of the body panels were SMC, others were still traditional fiberglass. As for Composite vs Compound; Composite is certainly more technically correct; however, with regards to historical Corvette references, most that I’ve seen, especially in earlier days before the internet referred to it as compound.
@@troyblackburn4522 I kept questioning myself, however I have two original paint 71 LT1's - one is a 3 Star survivor which has the Hood and maybe the rear lower exhaust panel made from SMC, I don't believe anything else is SMC but I would have to check the panels, I know the quarters door skins rear deck are press molded. BTW my cars are Brandshatch Green and the other is a factory Black car.
@@TheJagjr4450 i find it’s always good to question one’s self from time to time. There are so many variations that get phased in, it can be difficult to keep track of them all and we’re only human. To my understanding, SMC was like so many other things phased in over a couple of years. I’ve owned 64, 69, 77, 84 and 90s, with multiples of some of those years and I’ve also worked on other years.
Regardless of whether or not we get every detail correct or not, I’m going to say that we’re doing pretty well in terms of our knowledge. I had a conversation recently with a self proclaimed body/paint expert who insisted that his 1988 Corvette is made from traditional fiberglass and that it has factory gel coat 🤦🏻♂️. No one could tell him otherwise.
Excellent info. Thank you.
What resin did the factory use on 63-67 vette , polyester, polyvinyl? Would seem important for repairs ! Is the bonding compound the same for everything? Greatly needed editorial! A video on the different makeup of fiberglass components and compounds use for different generations of vetts would be greatly appreciated! Have watched MANY of your videos, excellent! Thanks !
64 convertible owner here. Do you do know of a good video to remove the windshield glass trim? Thanks
Will you ever do a video on 64-67 coupe doors and if you can modify those doors into 63 coupe door where the chrome molding goes? Or are you force to buy 63 doors coupe??? I have 65 doors and want to convert into 63 coupe doors , is it possible?? Thanks for any input.
How were they done at GM?
Is press molded still made from fiberglass?
Yes they are both fiberglass.
