I recently purchased an '80 MGB LE. It had been sitting out under a tree for some time. After washing multiple times to get the grime off, I could see the outlines of leaves and other debris in the paint. I compounded it out, polished, and waxed and it looked great. After getting wet a couple of times, the outlines of the leaves came back. Any ideas for methods or products to remedy this? Also theories on why this is happening...a friend suggested acid from the debris attacking the paint..also suggested as a desperate measure making a paste out of baking soda and applying to try to neutralize the acid.
Thanks!

You;ll probably get as many opinions on this as there are stars in the sky, but here's what I'd do (or try):

1. Buff the car with a power buffer using 3Ms Scratch and Swirl Remover for Dark Colored Cars (available at Pep Boys or Auto Zone, or...)

2. Buy the following from Zaino (https://www.zainobros.com):
Zaino Clay Bar, Z1 Polish Lok, Z5 Showcar Polish (for light scratches), Z6 Gloss Enhancer and (recommended for in-between washes - Z7 Show Car Wash)

On their web site, print out and follow their instructions. The first time around it will be quite a job, but once you've done the initial Clay Baring of the car and the Z1, Z5, Z6, it is easy to maintain after that. The Clay Car will probably do the most to cure your problem and the polish lok and Z5 will prevent any further moisture from reacting with the paint.

Scott - time to post your Zaino pics!

OK - just remember Bas, you asked! images/icons/smile.gif

I'm actually (sorry Bas) not convinced Zaino will be the ultimate solution to the problem you're describing because I have a nasty feeling the leaves have leeched some kind of acid into the paint etching it. If you've already used a pretty heavy compound you might try it again or even do some wet-sanding, then compound and polish. At this point I'd be afraid of breaking through the paint though.

Before doing all that though you might try another step (for shame Basil, seems you left it out of your instructions!), wash the car with DAWN or ULTRA-DAWN dishwashing detergent. It's horrible for your car normally but it will strip any grease and wax off the paint and possibly whatever the leaves have embedded into the paint.

Immediately do the clay-bar step slowly and methodically. Zaino's clay-bar is very good but Mother's and Clay-Magic are also excellent (please avoid using Meguire's clay-bar, it's terrible). Once you've clayed the car go ahead and go through the polishing and waxing, and see if it makes a difference.

Finally, there is always the option of trying another final product other than wax. I'm afraid it would only be masking the problem, but if it works - great! Zaino is a top notch non-wax final finish product and I swear by it, but a lot of people are going with Duragloss, NuFinish, and Mother's "Reflections".

Zaino is the most unique of the bunch and deserves some investigation, but it might be a tad expensive to use as just an experiment. If you have an otherwise great quality paint job Zaino will do wonders on it, but you can't just pop into the corner Autozone and pick up a $2 bottle to try so you might be tempted to try one of the other products. If you should try Zaino it cannot be stressed more that every last trace of wax needs to be stripped from the car before trying to make it work. I'll just say that the stuff DOES work and is entirely suitable for a daily-driver and contrary to a lot of information I've seen on other forums it works wonderfully on dark cars - better than most waxes any day, and lasts.

Although they don't really show any before/after comparisons with spots or "leaf" outlines, etc, here are some sample pictures of my Zainoed cars (some are "just been Zainoed", some are after having been done for months). The Corvette was purchased used and had some flaws similar to the ones in the 80LE from water spots, etc. We did the whole wash/clay/wash/Zaino process while rubbing out some of the spots with the 3M Swirl-Remover before the clay process - it has remained mirror-like since:

Finally this image is of the trunk prepped then waxed with Meguire's Hi-Tech Yellow Wax (paste, not liquid). It was, and still is an experiment for comparison's sake. It looks really good but I usually need to rewax it before a show to keep it looking as good as the rest of the car, whereas the Zaino can be wiped over with the Zaino detailing spray in a couple of minutes and look brand new.

tr3@tr6:
I agree with what's been posted, last resort would be a 1400 grit wet sand and full polish with clearcoat. After thoughts are car covers, I use them in the garage and in the parking lots, dings and paint protection.

Hi, these ideas are assuming you know how to run a machine buffer/polisher. If not take it to someone who does, no room for mistakes. All work to be done on cool car out of sun. wash CLEAN completly dry, so you know there is no grit on car. Wet sand 1500, good paper soaked, soft pad. short strokes, squeege your work.Dry entire area when done, 3M Finessett II polish with machine small areas at a time, to gloss,then 3M hand glase. more to it than this but to hard to explain, Actually all steps can be done by hand,but your arm will fall off.An opinion about clear coat on older LBCs, DON'T. to artifical a shine for the period of the cars. I bet I get yelled at for that remark.

Thanks for all of the ideas. I took the luggage rack off and went at the boot lid with 1500 grit paper, followed by light compounding, then polishing with an orbital polisher. I would have never tried that a couple of years ago but I painted a '70 Monte Carlo last year with pretty good results, so I was brave enough to give it a try.

The test will be over the next few weeks, looking to see if the stains/etches come back. Good thing is, the bonnet and boot are the worst, being large horizontal surfaces, so if it works, a significant part (the boot) will be finished.

The Zaino products look great, I'll be ordering some to finish this job and/or to use on my other, less problematic (ie, more show quality) LBCs.

Wish me luck, and thanks again
