Wet sanding & buff magic = big success!

[Yochach!]

I purchased my 97' 330 da in June and although she is in great shape mechanically she suffers from oxidation. Most notably on the front valence in between the bottom of the windshield to the non skid deck.

I read a ton of reviews about buff magic pro polisher and compound so for a $200 Amazon purchase why not right??. I began with that dreaded front valence and was pleased to see that it went from being very rough to smooth to the touch. I wasn't satisfied with the shine so after seeing a picture of a new 330 I got motivated to give it another whirl.

After reading up about wet sanding I stopped by the Home Depot and bought a sanding block and 2000 grit wet/dry. Only applying minimal pressure I wet sanded that valence area. After I was done sanding I hit it with the buff magic again and WOW!! It is literally a showroom shine!.

Sorry for the long story but I was very pleased with the outcome of this method and I'd like to pass it on. Here is a picture of just one area I've wet sanded/buffed/polished.

Don't bother, just get Presta Super Cut and be amazed! No need to wet sand any more. Presta gel coat compound is very mild for standard maintenance. Get the white wool pad.

I just did mine from the rub rails up with just plain old Meguiars Cleaner and Wax. Keeping it under cover and shielding it from our desert sun makes a lot of difference.

Wow! That's the shine I'm going for very beautiful finish. Unfortunately for me my 330 hasn't been under a roof. The oxidation on her is awful very chalky to the point of when you rub your finger against it you see white residue on your finger. Little by little I'll get the shine back and I appreciate all the input of what products you all are using

Where did you purchase it? I have found that the Presta website is too high. Try here https://www.blendsupply.com/presta-134501-super-cut-compound/

i got it at a local body shop supply store. they only had gel coat on the shelf and i asked for the super cut and they told me that the gel coat was the most aggressive product presta made. then they looked it up and realized they had the super cut at their other store but i needed it that day. i think i paid about $30 for a smaller bottle and i think they had a 1 gallon container for about $90 or so
