Just finishing up a couple rocker patches and a cab corner on my 03’ Silverado 2500. Wanted to thank you for helping guide me through the steps to make that happen. I’ve never done any bodywork so I used your excellent tutorials as a guide. Not gonna say it came out perfect but it’s way better than rust and it will last a long time! Thank you Jerry!

[@LakesideAutobody]

That's great to hear. You're very welcome - glad to hear the videos help. Every rust repair you do from now on gets better and better - that's just the way it is. Any time you want to send pictures of your work feel free - schoolvideolibrary at gmail dot com - Have a good weekend my friend :)

Really important DONT PUSH ON THE SANDER!!!! run the sander the directions of the panel and let it cut. When using a Da or 8 inch da pushing on the sander will make the panel wavy.

[@LakesideAutobody]

Great points Mike - thanks for your input. Have a good week - the Ghia is looking real good btw :)

[@ChipsAndSparksGarage]

That bondo hog sure saves a lot of work. Do you only use it for the 80 grit?👍

[@jamescon55]

You can use 36/40 grit to remove old paint/primer and or filler, depending the app. Just be careful when cuttin mud with the heavy grit as it can cut more than ya want IF not careful.

[@keithclark486]

Hutchins orbital air file with 120 then step down to 220 is what I use on large area's like that on 1'st blocking. We use to call those long sanding blocks Idiot sticks back in the day , lol.

[@jamescon55]

Yep, Hutchins air files are my personal go to's for most mud work or primer leveling whether orbital or even regular air file to just start knockin it down. Just a preference. Some guys use mud hogs, some use air files.

[@keithclark486]

@@jamescon55 On large area's a mud hog will wobble and if you get to close to high contours it will dig in So I use a air file to cover large area's for a flatter finish. I've never seen anyone use 80 grit to sand primer or use it as a body filler It's best to keep the mill build at a minimum.

[@jamescon55]

@@keithclark486 Exactly...

[@michaelmarusic8499]

👍🏻 Awesome job!!! I got a respirator with the pink filters like yours, was shocked how dirty the filters where when cut in two. Can you recommend what filter to use when painting? I know the charcoal filters only last a few hours, not handy for the DIY guys.

[@LakesideAutobody]

3M 07193 Dual Cartridge Respirator Assembly Organic Vapor - I get a new mask about 2 times a year. I guess you could say there's more than a few hours on the mask but I only use for paint - I really don't spend that much time putting on a coat though and I leave the garage quickly after. A fan expels the fumes by the time I get back for the next coat. I also read in the instructions on a different brand that if you "smell" anything paint when it's sealed to your face - that means the charcoal filters are done. Not sure if that's true but it does sound logical to me. I did a review on that mask btw - kzbin.info/www/bejne/lZm7mKmJgbB9g7s Have a good weekend - it's good to stay safe and protect you lungs so do some homework on that - let me know if you find anything real good on the topic too - like when exactly to change them out - right now I'm going by time and smell but that's probably not perfect - Jerry

[@jamescon55]

Don't forget to blow out pre-filters or anything else out to help extend the life of some of your filters. It works for me.

[@LakesideAutobody]

@@jamescon55 Thanks for the input Jim - have a good weekend :)

[@dwaynelejeune3508]

If one don't have a bondo hog, could a DA or Air file work? Thx for the awesome vids and tips

[@LakesideAutobody]

Yes - you could use that - the air file would get it straighter than the DA though. DA's a little small for blocking large areas.

[@christianmeyer6731]

Where you added the putty to fill the low spot, will you block it again before priming? Or prime and then sand it with the finish sand? In the same step on my project. Thanks!

[@LakesideAutobody]

I've done it both ways but I tend to block it first, then prime for finish sanding. Good question btw. Have a good weekend Christian :)

[@jeremymcnicol9585]

[@MH-on8ol]

Dang thats aggressive hitting high build with 80 grit on a mud hog. I would use 80 on a long long board to cut the highs down then do another coat of high build slightly reduced and go 180 220 and then 400. Looks good

[@LakesideAutobody]

Thanks MH - That is a bit aggressive but it does work if you work your way down like you say. I'll add that panel in on the next follow up video on this truck for now here's the first one - kzbin.info/www/bejne/nXq2YoeYq5x-rNk

Excellent video as usual. Wondering if you ever tried this primer which others have highly recommended. SpeedoKote SMR-210/211 - Automotive High Build 2K Urethane Primer Gray Gallon Kit, Fast Dry, Easy Sanding, Activator is included. ($89.00) I would try to give an Amazon link but youtube won't allow the competition.

[@LakesideAutobody]

I have not tried it - right now I've been using Auto Body Master urethane primer at times. I've heard good things about SpeedoKote so I'm sure it will measure up with the best stuff out there. That's a reasonable price too. Let me know how easy it sands if you do try it . Thanks for the support btw Irish Guy - have a good weekend - Jerry

[@zhengatozzy9904]

How deep of the scratches that primer can fill after finished the bondo work .

[@LakesideAutobody]

Feather fill can fill 36 grit scratches but it's always good to get your filler down to 80, your feathering down to 120, etc. Remember, feather fill is basically body filler that you can spray on so the rules are similar to bondo.

[@zhengatozzy9904]

@@LakesideAutobody I always start with 80 and end up with 320 on bondo. I think the grits above 120 is for shaping and feathering and anything under 120 is for sanding , maybe I am wrong 😀 And thank you for sharing your experience and knowledge.

[@LakesideAutobody]

@@MrSprintcat You're welcome. Just for fun Google: “Sail panel leaded seam” Factories have been doing something similar for 100 years. That’s why body shops have also been using this method for over 100 years with great success if done correctly - that’s the key - must be done correctly whether you lap weld, butt weld, or glue. Weld or glue your seams, knock them down and fill - simple :)

[@hobbyautobodyfun9315]

Jerry I used PLC Polyester primer before but they stop making it is the Featherfilled ever coat polyester primer better than that one .

[@LakesideAutobody]

I believe Ever Coat Feather Fill is the original and it's really good stuff - works great for me and has since the 80's. I'm not sure how it compares to the PLC but I'll bet it's very similar. Let me know if you try it and how you like it. Jerry

Why not use a inline sander? Then a quick hand block and done.

[@LakesideAutobody]

You could do that too. For big square areas I like the ND900 'cause it blocks in all directions. For long rectangle areas I like the long board better. Just a preference though - it can be done both ways - have a good weekend Doc :)
