Oxidation...go away!

**bufferdan** · 09-09-2004, 10:49 PM

I just purchased a 93 MR2 in red with no clear coat. It had heavy oxidation on the spoiler and light on the upper part of the body. I buffed it all out and applied some Klasse All-in-one and Glaze. Well the car set outside for about a week and the spoiler got oxidized again! Not as heavy but i still had to take some compound to it. Do i really have to buff/wax this thing every week? Is there any special technique and product i should use?

good luck

yeah..ive seen his posts before. Mine actually came out like his when i was done BUT as soon as it set in the sun for a week or so some of the oxidation just came right back! I buffed it out again about 4days ago with 3m fine cut compound and put some zymol on top and it looks like its comming back again. Im just talking about the spoiler though..the rest of the body is still fine.

sorry i have no clue, maybe you might want to PM him as he might know more about MR2s.

i have an mr2 you just need to keep on it. For the summer time i put on two layers of SG back in may and the oxidation didnt come back except some of the corner spots i may have missed. Try a sealant?

I have a 1990 Miata and that thing is a PITA to keep shiney. The only thing I can suggest is since it`s single stage paint try glazing it before sealants and waxes. Plastic and polyurethane panels are a pain after they start to fade so you just have to keep on em. Good luck man.

Im afraid im going to wear the paint down too much? So much red comes off each time.

Are you working by PC/Rotory/hand, you shouldnt have to buff/wax every week as long as you maintain it well. If you know the car oxidizes very fast then id go w/something that has great UV protection i.e. Zaino, BF, Klasse

heres some links to help you out

When paint fades quickly after polishing and waxing, the paint has died. RIP. It has opened up so much that it oxidizes very quickly. Sounds like new paint is in order....unless you want to wax it every other day until it finally wont even shine when that is done....

Does this mean that oils are no longer present or is there something else that has/can cause its demise?

No...it`s not a questing of oils not being present..more complicated than that...basically the chemical integrity of the paint has been degraded by UV, stress, environment, etc....In simple terms I guess you could say that it has dried out but it is really more of a weakening...the bonds of various components in the paint have been weakened and the paint opens up, more surface area to oxidize. Once the paint has been breached in this manner, applying waxes and polishes temporarily wets the surface making it appear better. The oils and other components do not have the ability to repair the broken bonds....but rather cover up the problem for a short period of time.

Paints, unlike waxes and polishes actually due chemically (catalysis) cure. Once these bonds have broken down...a chalky appearance of oxidation is present. When the damage goes deep...then waxing and polishing can no longer smooth out the surface and new paint is in order.
