Bondo Metal Reinforced Filler - High Strength Filler, Can be Drilled and Tapped - Will Not Rust, 11.2 Fl oz with 0.37 oz Hardener

excellent product.. :)

I've never worked with Bondo before in my life. I decided to fix a fender on my Porsche that had some minor damage. I got quoted a minimum of $1750 to fix a simple ding on a fender. One Autobody shop quoted $3800. Because it is a modified Porsche I must get "noob" prices. I watched a couple Youtube videos, which took about a whole 25 minutes, then spent another 2-3 hours mining away in "Bondo" talk on Reddit..after a quick afternoon ...I learned the "difficult" job and fixed the damage perfectly. Bondo is amazingly strong and is very easy to work with. The mixing ratio seemed vague so I went with 8 drops per 3-4 grams, on wax paper on top of a scale. Since I was in the garage with the door closed and it was late, I figured I could do this in my underwear since the garage was hot (it's summer). Working with Bondo produces a strong smell, so I decided to wear a filter/rebreather mask as well. My wife walks in to check on me as I am in my underwear, with a gas mask, using a scale to measure some drops on some gooey glop on wax paper at 2am. She said, "What are you...Walter White?". Mixed Bondo on wax paper, use "folding" action to mix it. Used these Spreaders, mostly the large one Dynatron 358 Spreader Spread it around to make it flat as possible, very akin to spreading icing on a cake. The bondo gets hard and tacky fairly quickly, within 1-2 minutes, so don't dawdle. Let it dry. Don't rush it. I let it dry 24 hours. I chose to wet sand it, even though nowhere recommended it...or said not to. I chose to do this to keep the dust down. It worked perfectly. I used 400, then 600 grit and hand sanded it. I went up to 1200 grit and thought it was smooth enough. This took me 3.5 hours because I am meticulous. At this point I was done. You may choose to paint your own car at this point. I am not that brave with my Porsche. Dropped it off at an Autobody shop and they charged a very fair price to paint the fender. 10/10 would do it again.

Can is 4 inches tall and 3 1/4 inches wide.Yes a bit pricey but so is the other leading brands.This stuff dries hard as a rock...you really dont need much hardener...its a clear liquid(the hardener)so a bit tricky to use but just use an amount equal to whats in the can....so 1/4 cans worth of bondo..use 1/4 of the tube.Mix it up...you dont have to mess with it fold it over 10 times and its done....its going to harden..dont worry.... it is a bit hard to sand when put on thick but thats what grinders are for...lol.Again its solid as a rock...i cant attest to longevity.I fill big rust holes with spray styrofoam...and then knock it back a little then fill with this bondo.I have fixed big holes in rocker panels this way with good results.Not perfect mind you but from 10 feet away you cant tell and it passes inspection.

Great stuff

Great product but the cost for such a tiny amount is a bit deceiving.... Does an excellent job but it doesn't go far...
