Thread: need help with body work

Tweet

ok i am getting my truck ready for next year so i can paint it and stuff i know that i need to remove all the glass and take the doors off. but what i am wanting to know is it has some bondo init and if i should sand it down and find out why it is there and then put more back if it needs it. and if i should use a certian primer what spray gun i will need. and all that i have a chambell hausfeild compresser and this is all the stuff it does and how much air it can hold
5.5hp 120 volt, 26 gallon asme tank, 6.5 scfm@40 psi, 5.1scfm@90 psi, 125 psi Max.

Well, use the primer that is made by the paint company your using, otherwise, they won't gaurentee the paint and there may also be adhesion problems. You should take the bondo out and put new in, if it needs it. For a paint gun, you should get a high quality gun, it really dosn't matter if it's HVLP, that stands for high velocity low preassure, it is basicly approx 20-40 % more efficent than a standard gun ( 75%-90% hvlp, around 50% regular ) but are gennerely more expensive. I bought just a high quality siphon feed for a mere 25 bucks. For the nozzles I'm not shure of the sizes but I do know that the larger nozzles are used for primer, smaller for paint.

There will be in most cars rust & rust thrus under the bondo. Remove the bondo & replace the metal. w/new metal(weld), Epoxy prime the area & do the bondo work.

If you do not have welding skills go to a local vocational school or farm the work out.

well my uncle is supposed to be teaching me some welding. but i looked at the back of the metal and it didnt have no rust on it it just had the holes for the side molding and stuff. and the guy just liked to use bondo but is there a different way to feel the holes with out useing bondo???????

ya spoda weld up the holes then grind them smooth but, don't create too much heat at once or the metal will warp a little , try to use a grinder wheel that dosen't create to much heat, it will help.

Yes you can weld the holes shut. It does not take long to learn how to mig weld, plus its worth it. The only thing I would suggest is use gas when you mig weld it makes for much smoother welds and is less messy.

Truckguy, don't ever bondo holes, the bondo will pop out. Use a MIG welder and put everything down low and only weld a inch to two inches long in one spot and move around. Like Matt said, welding in one spot for a good amount of time will warp the hell out of metal, same with grinding, be careful on that too. Take all old bondo off, sand the whole truck to bare metal if possible and get ALL rust and black spots in the metal... Black spots are bad, get rid of em. Spraytech here can mention a good gun to you and I know what it would be.... The new 3M gun. Hope this helps man.

ok well is there a certain mig welder that i need to get cause i plan on doing some more progects later after i get this one done and i want one to last for awhile. would the campbellhausfeild mig be good or do i need a better one?????

For general bodywork, any Mig would work but, I would recomend the 349 dollar lincon welder, it's a good named welder and it's a good price, it's not the biggest/ best welder you could buy but, it would deffenetly do bodywork. it is an 85 amp unit and can weld 1/8" steel. The cambuls hausfeild from Walmart is a 115 unit but, walmart quality ( they force there suppliers to send out products to other contreys for assembly and they use cheaper parts, in the end, the price can be marked up over 50-200% and still be cheaper for the customer ( My mom works at walmart and I watched the walmart haters special on TV.) also, approx 85% of the American population buys an appliance from walmart every year. to give an exzample of walmart quality, look at a Remmington gun pricing book, there is a listing for walmart and a listing for all the normal companys, Walmart listing is much less.

yeah i dont like walmart i got mine from true value hard ware store. i will see what i can find. you said 349 dollars is that how much it costes i just want to make sure??????.

349.95 Summit part# LCN-K2185-1 I just looked at the new summit Mag to be shure.

ok well it mite be awhile before i can buy one for myself but my uncle has a mig and i should be able to pay him to weld them up.
and as for the inside of the truck should i just sand all of it off to????????


Thank's

yep, sand, then wetsand with 400 inside.

Dan, look at lincoln or if you got a bit of money to spend check out some Miller welders. If you can then try and get a 220 volt so you can weld a wider range of metals and different sizes, etc. The 110 v won't be able to weld bigger metal and not so great on frames either. You can weld with a 110 on a frame but 220 would be better. Of course it will cost more and quite a bit more but to me it's well worth it and it will last you forever and the duty cycle will be higher (weld longer with it full blast).

ok it will probly be awhile before i get a welder but about painting it is my compressor good enogh or do i need another one???
