Paint/rust removal

H

HIG

I bought this car about a year ago for a project with my son and I'd like to get the car stripped down to bare clean metal and at least get it epoxy primed so it doesn't get worse.

What are my options for stripping it and removing the surface rust? Should we carefully sandblast it to clean it but I know you have to be careful not to warp the panels or would DAing it then Naval jelly work better/safer.

May I have some suggestions and processes?

Thanks, Steve
 
original paint will come off easy with 80 on a da. if you find rust issues then naval jelly works fine.

Thanks for the reply, I will do some reseach on naval jelly. I remember reading here it's important to keep it wet while working with it.

Thanks again, Steve
 
Is there a need or process to neutralize the naval jelly and how quickly will the area re-rust? Just curious because I recently spent a ridiculous amount of time spot blasting the roof and rear wall of the Chevy truck I am working on. There were specks of dark brown rust on the roof where the paint broke down and infinite pinpoint scratches on the back wall. Would naval jelly penetrate and lift the rust out?
 
put some saran wrap over the naval jelly keeps it from drying up so quick.
 
This stuff works as good or better than naval jelly: http://www.homedepot.com/buy/klean-strip-1-gallon-phosphoric-prep-and-etch-gkpa30220.html

The last time I bought this stuff it was $12/gallon, I keep 3-4 in the shop at all times. A quart will do that hood. Lay out some paper toweling on the panel and saturate them well, works well on vertical surfaces this way also. Pull back the towel after 30 minutes and scrub with a scotchbrite, pull the wet towel back over the area and let it set for another 30-60 minutes and keep repeating till the rust pits are clean. With any phospheric rust remover it's also necessary to do a water wash while the product is still wet when your done, if it dries out during the rust removal put some more acid on it. Definately wash when done!
 
Thank you Bob! I really appreciate you taking the time to lay out instructions and the link. I'll be sure to scrub it good and wash it twice for good measure. Thank you satarules too, I found that useful when using paint stripper.
 
Thanks for all the replies and the link to Home Depot, now I just have to get my Camaro done so I can work on the other Camaro.

Thanks again, Steve
 
Try a krud remover...the one that looks like a hard black sponge and attach it to a grinder..I bought mine ar Home Depot $10... works good.

I started this thread about a Camaro I have sitting in my yard and now I have a question about my son's Jeep.

This is what I have:



Stripped with the shown fiber wheel then 80 grit on the DA (the DA'd part is on the right):





It looks like the 80 grit is getting the remaining rust, should I use some phosphoric acid just to be safe or will the epoxy seal up any pits that were missed (I'd probably spray 3 coat then some regular build over that)?

Just wondering the best way to finish the hood ,

Thanks, Steve
 
i use milkstone . it is 54% phosphoric acid . most any other product is 15-30% . because it mixes with water it is pretty cheap. used straight it does a really good job on pits.

Evaporust works great overnight and you can use it over and over.

I believe that product is only good for a pre determined amount of rust removal. So it gets weaker as you reuse it.

So you guys don't abrasive blast panels? Seems like it would be much faster.

Some will say they can get away with it but I've heard more horror stories than successes. Leave the sand blaster fro frames

I used the naval jelly trick and worked very well. Had a '70 Mustang that the roof and hood were heavily rusted.
