How to repair a GM dually plastic bedside!

On this episode of Midnight Garage, I take you through the steps of repairing a GMC or Chevrolet thermost polyurethane plastic bedside!

[@tonynightingale4400]

Amazing ingenuity on your part, nothing is impossible if you put your mind to it , and your mind was working well that day ..spent all my day spraying so I thought I'd relaxe and watch you working...lol ❤

[@Johnnymidnight]

Funny how we’ll work on cars all day, then watch people working on cars 😁😁

[@stanleyhaddix9432]

I’m going to fix my dually fender now. Very helpful video.

[@lbj808]

Damn!! I have the exact same damage on my dually bed! Couldn’t find anything on KZbin to fix it but your video popped up out of nowhere!!👍🏽👍🏽…there is hope. Mahalo for the video ..Aloha🤙🏽🤙🏽

[@Johnnymidnight]

Cool, I hope it’s helpful 👊🏼

[@brcron007]

That turned out Great on a Budget and Ingenuity too.

[@johnroberts1206]

Thank you for the video I got to replace half my quarter panel and had no idea what type of material I needed to use.

[@c10addiction22]

Thanks very much for posting these videos! They're a great help for your fellow rust-belter's. Cheers

[@Johnnymidnight]

Awesome, I’m glad you find them helpful 👊🏼

[@anthonyardizzone3792]

A repair for dually fenders that can be warrantied is a money maker. Thank you for sharing.

[@MrHugawa]

wow, that repair is perfect... looks amazing

[@Johnnymidnight]

Thanks 👍

[@tracyrenko4171]

That’s very good to know how to fix that problem thanks

[@delbertgrubb1341]

Nice work, subscribed after this video, love your paint booth

[@Johnnymidnight]

Thank you, much appreciated 👊🏼

[@giovanni27772]

Don’t you think fiberglass cloth and resign on the inside to reinforce it and fiberglass filler on the outside would’ve been a lot stronger ? That’s at least how I did mine

[@Johnnymidnight]

Nope, they’re not fibreglass, a flexible filler is necessary,or it will just break away if bumped again

[@BryanClark-gk6ie]

Repaired several of those' I always drilled a series of 1/4 holes on both sides of the split for squeeze out to adhere to the fiber glass tape.

[@Johnnymidnight]

That’s a great idea, I’ll steal that for next time 👍🏼👍🏼

[@gabriela7x917]

That does sound like a great idea!!!

[@jeremyzap]

Very good video I’m doing repairs on one as well cuz they don’t make them but I’m using fiberglass and resin to repair and bondo mixed with fiberglass to fill in the repairs. Finally someone made a video of these fenders. There is nothing out there to show what ppl have done to repair. Thank you for the good video

[@DHeck-le5mm]

Absolutely an awesome video!!! Can I ask what is the trick of getting the fiberglass well liner out and back in without taking the bedside lose?

[@Johnnymidnight]

I loosen pretty much everything you can reach in order to get those out, always a pain in the butt….🙃

[@DHeck-le5mm]

Hey Johnnymidnight Do you loosen the bed side bolts to get the fiberglass wheel well out? I do have concerns of flexing the bedside too much on re+-installing after bedside has been repaired? TKS

[@Johnnymidnight]

Yes, I loosen pretty much all the bolts up the front that I can reach, but they’re still tricky

[@onlywoodard6078]

Love it !! Exactly what I needed !

[@nfibailey]

Great video..I'm working on the exact bed..with the exact problem..just ordered my plastic surgery stuff. Thanks again so much.

[@RBoysMedia]

How’d it go?

[@jeffroutzahn9195]

Best video on these bedsides. Great job

[@danamcintyre3565]

I'm thinking it could be used on plastic bumpers ?

[@Johnnymidnight]

You betcha, I’ve repaired lots of bumper covers, cladding, Harley fairings and bags, all kinds of plastic with this stuff. It comes in flexible and rigid

[@zacdrilling4554]

Boy did that turn out great, nice work. Did you only use that blue stuff or after your second coat did you use traditional body filler before your primer coat??

[@Johnnymidnight]

Thanks, completely done with the flexible plastic filler, I try to never use regular filler on plastic, cracks too easily if it flexes

[@brandontittle5762]

Great job on the repair

[@Johnnymidnight]

Thank you 🙏🏼

[@joestone2068]

Nice job 👍👍👍

[@Johnnymidnight]

Thank you 👊🏼

[@jessecontreras2664]

Beautiful

[@jessecontreras2664]

Thank you

[@barryhunt5357]

Great video and great repair! I just subbed to your channel; I've been watching for a week now.

[@Johnnymidnight]

Thank you, I appreciate it!

[@jamieschentag1027]

Nicely done good sir, I have cracking happening at the body line just above marker lights. Most likely it was repaired prior to me owning it as the box was completely rock gaurded. I was wondering what you used to sand up the plastic filler to get it to look so beautiful? Thank you in advance for making this video as it has given me the motivation to start these repairs on my 07 Classic dually. Cheers!

[@Johnnymidnight]

I usually just sand it with 120 at a fairly low speed, the dominion sure seal plastic surgery sands pretty nice

[@christoherbriones8326]

Thanks for the info ..good job!

[@gabriela7x917]

Man that was awesome! Thank you so much! I gotta get that stuff. I want to fix my 04 Stepside. It's broken, has 2 ugly holes, one is around the taillight

[@Johnnymidnight]

Glad it helped, nothing to lose by giving the repairs a shot 👍🏼👍🏼

[@Fullyautoz]

@@Johnnymidnightwe’re would you purchase the blue epoxy?

[@Johnnymidnight]

@@FullyautozI get everything from Lordco auto parts

[@markherron69]

Beautiful work! Thank you for taking the time to share your secret technique. I have the same truck with a crack that is opening up in the exact same spot you made your repair. I can probably handle the repair, but I am uncertain with my painting abilities. Where are you located? I would live to bring my truck to you for this repair.

[@Johnnymidnight]

Thank you, I’m in Quesnel BC

[@stan525]

Nice job looks as new. ? do you think that Dominion plastic repair will work on a vinyl dash crack

[@Johnnymidnight]

I never considered that, but I bet it would, the stuff is pretty awesome

[@bluecoller]

life saver Video. I have to repair my fender as well. but no fenders to be found by the shop. so i'm going to try this. i do have a some questions though, like what grit was used to prep the area for the filer for the best adhesion?

[@Johnnymidnight]

100 grit is typically what I use 👍🏼👍🏼

[@bluecoller]

@@Johnnymidnight thank you for your reply.😁😬

[@bluecoller]

hi John , as i read the box of Plastic surgery repair . it state to prime with flex primer and to clean the area with sure seal sure solv. or low VDC surface clearer. so my question is, is this a must used or is other brands ok to use?

[@Johnnymidnight]

Totally fine to use other brands along with it👍🏼👍🏼

[@proshielder60]

There’s 2 places I’ve found that still make them, one in Cali and one in PA

[@Johnnymidnight]

Ah, good to know, no longer available from GM

[@williamv-w2z]

Nice work:>)

[@Johnnymidnight]

Thanks 👊🏼

[@dmsteele92831]

I have this same model truck and same cracked fenders, going to try this! I'm missing pieces though. Do you reccomend fiberglass repair on those 1st?

[@Johnnymidnight]

Fibreglass won’t adhere to the polyurethane, and isn’t flexible. If you can get a wrecked bumper cover from something, or a piece from a wrecked bedside, that you can cut to fit the missing piece, it’s a better option.

[@jankosgarage]

How many kits did it take? Thanks

[@Johnnymidnight]

I believe I used 2

[@jankosgarage]

@@Johnnymidnight thanks! Have a duramax bed to repair hope ot turns out as good as this one

[@Johnnymidnight]

I’ve repaired several with this plastic surgery, and have never had a problem, for what it’s worth, I highly recommend it 👊🏼

[@robertsmith5525]

do you have trouble heating the shop and paint booth when the cold weather arrives? Canada brrrr...

[@Johnnymidnight]

I have radiant heat that works well, but it’s an awfully big area, and an old shop… working is fine, but once it’s 25-30 below it’s too cold to paint

[@n.hathaway3290]

Is there a trick to get the inner liner in and out without removing the bedside?

[@Johnnymidnight]

I’ve always managed to get them out by unbolting the braces, and the bolts up the front. It’s still very tight, but the bedside can be pulled out just enough

[@scottwhite228]

what was name of flexible plastic filler. I have both sides to do?

[@Johnnymidnight]

I use Dominion Sure Seal plastic surgery, 3M also makes a comparable product, yes, backside definitely has to be reinforced

[@scottwhite228]

@@Johnnymidnight lol both fenders to do

[@alsaku33]

Do you have the exact part # for the product you used? I see that brand offers many different types. Please let me know.

[@Johnnymidnight]

XPST/4008, that’s the flexible one 👍🏼👍🏼

[@alsaku33]

@@Johnnymidnight Thank you sir!

[@robertsmith5525]

You need to put out some new videos, I binge watched your other videos

[@Johnnymidnight]

Cool, thanks! I try to have a video every Friday 👊🏼

[@andrewpate9157]

Where did you get that plastic surgery stuff from?

[@Johnnymidnight]

I get all my stuff from Lordco auto parts

[@johndominguez9672]

How much to do that to my same truck

[@Johnnymidnight]

Every repair is different, can’t say without seeing the vehicle. This one was a while back, I believe it was around 1500 range

[@robjones8257]

How much lol and where do I drop it off

[@Johnnymidnight]

Just drop off here in BC with a blank cheque 😁😁
