Severely Oxidized hood

[kdonovan]

Hey whats going on? Im new to this forum I have a question to ask because Im stumped on trying to revive this hood, it keeps fighting me. I have badly oxidized hood on one of my triaxle dump trucks. The color is red Ive tried various things from people offering there different ideas or input but nothing has worked thus far it just keeps returning back to the oxidized look. What can I use to cut down and get this paint back to a nice gloss.

Thanks

Hmm I wonder if it has clear coat failure. You said it keeps returning back to its oxidized state, so I'm thinking there isn't really anything you can do at this point besides repainting.

Re: Severely Oxidized hood

Im not sure to be honest, I was thinking the stuff I was using just fully wasnt getting through the oxidized layer

Re: Severely Oxidized hood

When you polish it, are you getting red residue on your pad or cloth? If so, it could be single-stage paint, without a clear topcoat. You may want to read this article on restoring single stage paints; http://www.autotraderclassics.com/ca...sationId=21363

I've done the process a number of times, forcefully working #7 Show Car Glaze into the paint, with very impressive results. Polish first, compound later sounds like a backward process, but it works amazingly well on parched single stage finishes.

How about a pic?

I can get it like this but then it always goes back to how it is on the right

Re: Severely Oxidized hood

How long have you had the truck? Always looked like this?

Do you get red on the applicator from any other panels?

Re: Severely Oxidized hood

Ive had the truck for about 8 years it came from virginia, The other panels are fine, I believe this became like this because it had sat on site one whole summer and wasnt taken car, such like wash, wax, and maintain... It had sat in direct sunlight, what is like this is the visor, top of the hood and top of fenders all exposed to the direct sunlight where as the side of the fenders and doors werent. Since that summer I have built a garage to store all my equipment. With this truck I have brought everything back besides these affected areas that i express my concern about on here. I believe the place I bought the truck from did a cheap paint job to make the truck look pretty to be sold

Re: Severely Oxidized hood

Well, was thinking if the other panels were not showing up red, that would indicate the hood had been re-painted.

Also, just making sure you had not seen the clear coat peel off or anything. The base coat of a cc/bc system will be a matte paint, hard to make shine.

So it seem to be a poor single stage paint.

What ideas, products, techniques have you tried so far? No point duplicating anything for no reason.

Re: Severely Oxidized hood

I have used several compounds found at your local autoparts store, I have used a buffer, and also attempted by hand , Ive attempted restoring it in a well shaded area or in my garage. I believe you are correct with the poor single stage paint, it did have a shine prior to that summer. I have also tried a product I saw at a truck show however I cant think of the name of hand. I was reading on line for badly oxidized paint that to use meguiars 105, then 95, then 85? is this sound correct

Re: Severely Oxidized hood

OK, let's hold up a second here....... the presence of color transfer onto an applicator could mean one of two things: single stage paint, or a failed clear coat that is allowing you to actually contact the color coat that has been exposed. Both situations, if left unchecked, will revert to a dull, oxidized appearance over time, but the failed clear coat will revert to that ugliness in a matter of weeks, if not days. And a failed clear coat generally won't let you bring up a very high, clear glossy finish anyway. Looking at the picture offered up, it sure looks like a single stage paint job that is continually fading back due to some level of neglect during its lifetime. And a single stage paint job will tend to look better longer if well maintained as opposed to one that is severely neglected and then "brought back".

kdonovan, it looks as though you've got a process down that will bring back the color and gloss, but what are you doing to then maintain that finish? Using any compound, whether ours or anyone else's, is only enough to restore the color and gloss, not protect it and keep it looking good. Once you've used whatever on it to bring the color back, what wax or sealant are you using to then protect it? This is a critical part of the whole equation, and if you skip it you're just asking for a quick fade back on the color. Unfortunately, if the paint is really hammered and it was indeed a cheap paint job, then you may find that you need to wax almost monthly with a light cleaner wax to keep it all in check. ColorX is great for this, especially when applied with a DA buffer.

We are a bit concerned that you've been going over this repeatedly with different compounds to continually correct the issue. That can, collectively, be a very aggressive way to keep the paint looking good and can lead to burn through faster than you might think - especially on a cheaper paint job.

So..... how often have you done the correction step? How quickly does the paint fade back to this dull, white, chalky look? Are you using a wax or sealant after the correction?

Re: Severely Oxidized hood

Well, not that those couldnt work... but wouldnt be the usual way of doing it.

Is your buffer one of the small orbital types from the local store? Or an actual rotary?

#105 could work, but if the paint is that dry, you will likely get a lot of dusting and gumming up, and not much working time.

#105 or Ult. Compound could be good options (UC has less oils and is less likely to dry up as fast, but is a little milder). Could try working them in a bit.

One other possibility would be getting some #7, and working it into the paint a bit, maybe even 2 separate coats, to try and make the paint more workable. Then use the UC/#105, and a coat of #7 after, then wax.

If it is a really bad paint job, it may just be failing of course. But of you want to get a few more products to try, those are some ideas.
