Orange peel prone to oxidation??

[noobwaxer]

hello, i bought a 1990 celica gts red a bit over a year ago, when i first got it the hood was oxidized.... i was told it was repainted.. i used 105 and 205 porter cable and it looked good for a couple days, then rain hit and got water spots, then fully oxidized again by now... will wet sanding fix this problem?? was thinking wet sand till glass finish... so no orange peel and it shouldnt be prone to oxidation right??

Any pics of the hood?

Re: Orange peel prone to oxidation??

Can we assume this is single stage paint - did you applicator pads turn red when working on it? If so, yes, it's single stage. If not, then it's a base coat/clear coat and you could actually be dealing with a clear coat failure situation in which case the only fix is a repaint.

You mention using 105/205 but did you wax after?

Re: Orange peel prone to oxidation??

yup the pads turned red so its single stage

i put wax on after wards, it didnt seem to last long, i think i used some spray type acrylic wax

i dont have a picture of the hood but if needed i can get one but the car is kinda dirty at the moment

i did try to wet sand the hood in a small block to test it out, i used 2000 gritt but that didnt remove all the orange peel, slight bit of oxidation coming back in the test spot but not as much as before.. oxidation on test spot not as noticable till you look up close

i dont want to bother removing the oxidation if its just gonna come back next year so would like to know if the wet sanding till glass finish will prevent this oxidation to come back

Re: Orange peel prone to oxidation??

i was probably wrong about the oxidation coming back 2 days later in the first post.. it was actually probably a week but took a little while to build up full oxidation again..

Re: Orange peel prone to oxidation??

this is what it looks like now

the test spot i did, small oxidize spots coming back, middle looks fine but theres actually small dots all over.. the test spot still has orange peel, 2000 gritt didnt remove it all... which gritt should i do next?? 1500 then 2000?

Re: Orange peel prone to oxidation??

noone??? was my posts to hard to under stand?? i want to know if orange peel will cause oxidation cause i keep getting oxidation... wetsanding till no orange peel will not cause oxidation right?? the pics above is orange peel and looks kinda like a basketball

Re: Orange peel prone to oxidation??

Yep, I'm confused.

Orange peel and oxidation are two unrelated things.

So no, orange peel does not cause oxidation. Also, if you do manage to get rid of all the orange peel, it doesn't mean the oxidation won't come back.

Re: Orange peel prone to oxidation??

if my orange peel is not causing oxidation then i think its water spots.....

i noticed last year right after i cut polished the car nice and shiny, the next day when water hit it, it turned into water spots which are also very hard to get off, its like the water marks are stained into the paint, over time all the water marks turn into oxidation....

so i guess now i need to find out how to stop water marks?? water marks are formed on orange peeled paint right?? makes sense to me cause water is trapped in the orange peel groves??? i dunno just a guess...

yeah i should of thought of this earlier... the cause of my oxidation is water stains!!! how do i prevent water spots, i mean my other car never gets water spot stains and i dont even dry it at all, why does this car seem to get it??

Re: Orange peel prone to oxidation??

Water stains aren't caused by orange peel either.

Orange peel is not your problem. Most paint finishes have some degree of orange peel these days - even brand new factory paint jobs.

I think we need to go back a bit here...

So you tried M105 and M205 via PC and that fixed the problem. When asked if you applied wax afterwards, you replied that you used:

some spray type acrylic wax

Frankly, that doesn't really sound good enough. You need to apply a good, durable liquid or paste wax or sealant. I would suggest Ultimate Liquid Wax or Ultimate Paste Wax.

...But even before that, and given that you have single stage paint that looks like it was neglected / oxidised / dried out, it would greatly benefit from a coat or two of M07. This will add oils and "moisturize" your paint, prior to sealing it in with a good wax/sealant.

So you would go:

M105
M205
M07 (maybe two coats)
Wax

Re: Orange peel prone to oxidation??

I just did a 92 Celica.
I guess I didn't do a post on it so I'll share it here

I washed and used a Nano Skin Auto Scrubber due to it being so oxidized.
The Auto Scrubber scrubbed the paint clean and I mean scrubbed it clean, the water run off was full of paint.
After that I used my MF pad and M105 compound to polish the #%$% out of it!
Then M66 to clean/polish and protect it.

So I'd say you'd need to use a compound and rub it out.
You have to get the paint clean and flat in order to make it reflective. Then you wax, seal or coat the paint to make the reflective shine last as long as possible

Before Marioization





Zero Reflective quality


After, it still needs a bit of work but that wasn't in the budget. But it's got a shine, the paint's clean and protected.

Re: Orange peel prone to oxidation??

i used this for my wax http://www.werkstat.com/acrylic-jett-trigger.php i think its this one, might be a different one but its from werkstat, i actually like this stuff, its easy to put on and last a good while

that nano auto scrubber thing is sweet, dont even need to clay which saves time.. only if i could find out where to get one...

im thinking maybe i didnt get all of the oxidation off the first time i did it so it started spreading again... im using the crappy noob porter cable thingy and i think its just too weak for 105/205 right?? i did use foam cutting + polishing pads... thinking maybe i should use a microfiber flat pad or one of those flat pads instead of foams...

does meguiars have an online canadian store i can buy some flat cutting pads from and which kind should i get for cutting.. the flat cutting pads seems like it will soak up less compound then the foam pads i have been using... i have been using b&s cutting + polishing pads foam pads

Re: Orange peel prone to oxidation??

so i been thinking i should wet sand with 1500 then 2000 to get a mirror look, i dont like the orange peel look.. and with the wet sanding it should remove all of the oxidation and a good chance it wont come back im hoping.. then hit it with 105/205 and maybe the m07 stuff if i can find it... i just hope that the oxidation wont come back after doing all this work all over again.. to be honest i dont even wax the car much, its just too much time to clay bar then wax.. but after cutting and polishing ill always put a layer of wax to finish the job properly... also since the body panels been repainted the paint will be thick enough to wet sand, i dont have a paint thickness gauge but i dont really care if i mess up with this car, yolo right..

Re: Orange peel prone to oxidation??

First off, just to confirm: orange peel and oxidation are totally unrelated and the presence of one has nothing what so ever to do with the presence of the other. It's as unrelated as asking if blue cars are more prone to getting flat tires than green cars are.

Now, on to the important part of this post - getting rid of various below surface defects (oxidation and water spots) and the potential removal of orange peel. Let's deal with the orange peel issue first.

If you wet sand with 1500 and then 2000 grit odds are you will indeed remove all, or virtually all, of the texture. But, are you prepared to then remove your sanding marks? It sounds like the only buffer you're using is a Porter Cable DA and that's just not going to cut it (no pun intended). If you finish sand down to 3000 grit then our DA Microfiber Correction System on that PC should be able to remove sanding marks from this single stage paint. But, you mentioned that this is a respray but do you know how long ago it was repainted? You can not automatically assume that just because it was repainted there is plenty of paint on it and you're safe to wet sand. This is especially true if you have little to no experience with the process. It could be that this was a cheap, thin respray and that's part of the reason your oxidation is coming back so soon. Or, it could be that you're actually doing very little to remove deep oxidation but instead are just doing a decent job of hiding it, which could be the reason it's coming back so soon.
