The Bondo trick you don't know... Faster, Easier, Improved Quality ! DIY Auto Restoration

Here’s a tip. I’ve been doing this for years as-well sometimes when it dries it may stay a little bit tacky and gum up your sand paper so I used wax and grease remover on a shop towel i give it a quick wipe and let it evaporate it removes all the stickiness and sands perfectly!!! 👌🏼💯

Yes, a great idea! Been doing it myself for over 20 years. One other use for the fiberglass guys, (I have been building fiberglass parts for decades) I always hated gelcoat as it is brittle and cracks. (and not cheap) I mix 1 part fiberglass resin with 2 parts regular Bondo brand (like you) to make a "thin-ish" brush on coating. (33% resin) I even use the fiberglass hardener, instead of the Bondo hardener. It sands easier, no pinholes, and is flexible so it doesn't crack like gelcoat. Plus, it's great at hiding the fiberglass matt/cloth texture. I also use it to bond on automotive parts, great adhesion and quick finishing.

I took your advice and 30 years (off and on) of doing body work I've NEVER enjoyed working the mud! But now, I wanted to create extra dents to fix 😂... I'm so freaking glad I learned this before death comes knocking 😅

Correct, I am a fiberglass boat builder, bondo is a polyester body filler so you use polyester resin to thin it, the common resin for fiberglass work. I figured this out on my own when I opened a can of Bondo and it had dried out, it works and holds up over time. What you end up with is something like a glazing body filler. Styrene is a thinner for body filler and resin. It's a game changer especially good for beginners.

I,m 68yrs. old! Spread my 1st dent in my dad,s body shop when I was 12yrs. old and seen plenty before that one while emptying the barrels,etc. There was a product called "Bondo- Honey" he bought and the guys used it just for that reason. This was in 1968 folks. Lacquer primer and nitro-stan (red putty)! No mig welders, you brazed a new qtr. panel on the vehicle! Excellent video just the same! Jeff Dusti Shirley, Ma.

I've worked with Bondo many times over the years, and I NEVER knew this. Outstanding tip. Thanks so much!

Straight forward instructions, just great. Other YouTubers should learn from this guy

I paint 2-4 cars a year for side work. This will make a world of difference for me. Thanks for taking the time to share

I just learned about this from Bad Chad. He didn’t explain the mix ratio but you did so thanks for that. You didn’t mention any hardener change but I’m experimenting with that as well. Too often I’ve had set-up issues before I’ve finished the application. If I learn a good ratio that gives me extended set-up time I’ll be a happy camper. Thanks again for your demonstration. Good information.

As a auto body tec and auto body painter, I can tell you we used this same technique with the fiberglass resin to make the bondo flow better with eliminating pin holes. Really works! We did it in the 1990s in our shop!

I appreciate your tip. I’m actually a woodworker that uses Bondo to fill voids on surfaces that will later be painted. Your tip will save me a lot of sanding. Yep, Bondo works fine on wood - if, and only if, you’ll be painting the project.

You know. This is actually genius. I was asking the guy at the paint store what makes the expensive bondo so much smoother and easier to spread than the cheaper stuff and he said. “Idk I guess they just use more resin” and I dint really know what he meant but this must be it. I tried this today and it works perfect. My first batch I made slightly to thin but after that I got it spot on. So much easier to work. Appreciate this. You gained a sub.

Rondo!! Sprayway customs (another channel) has been using that forever, but I will say, he’s never really explained how much to mix. Great video man! Thanks!

I'm not an auto body guy, but I do use Bondo for woodworking projects that will be painted. This is a great tip that I will definitely use, thanks!

You're absolutely right I've been doing this since 1983 and it works amazingly!

Man it appears lots of people have been doing this same thing for years , so what rock was I under dammit!! Thanks it only took me 50 years to find out Lmao 🤣

Great job. I so enjoy your videos. They’re so well done and I have picked up so much watching your videos. I’ve been a mechanic for over 50 years but I’ve never done bodywork and you’ve been a huge help. Thank you. 👍🏻

What an excellent trick and tip, I am always grateful for gaining knowledge from someone else's knowledge that is proven to work. Thank you for the great tips.

Crazy! I’m grateful to have stumbled upon this video . I enjoy doing body work and working with bondo. I also thoroughly enjoy working with fiberglass and resin but Im self taught and for that I rather good at it but with this trick I believe will take my skill to a whole new level with out a doubt. At the moment I’m working on refurbishing a boat I picked up for basically free . Has need a lot of resin work and I’ve already done a decent amount on the hull and plenty more to come. Awesome I came across this old school trick ! Thanks for the video and thanks everyone for the comments they have also taught me a things of two as well! I appreciate it guys !

I caught a custom builder show couple years ago, and he mentioned that bondo and fiberglass resin worked very well together, I was wondering why. Thanks for the explanation.
