On a 93 vette I assume it has a hard clear coat, if i jewel with m205 and a black pad will that be fine or do I need to follow with 85rd for further refinement?
 
What color is the car? I recently corrected a black '93 ZR-1 and the paint was on the hard side. I planned to finish with 85rd and found it didn't react well with the paint. In '93 GM used a new 2 part paint on the corvettes. Not sure if this was my issue, but I ended up finishing with 87mc instead. Looked outstanding when done. I would recommend a test spot with the 205 before wasting your time jeweling the whole car. Inspect in the sun. If you like the results then you're good. If you think you can improve it, then try a finer polish for jeweling.
 
Ultimate compound by Meguiars first on orange pad with pc7424xp then I did M205 on black pad. Do I need to continue with 85rd?

IIRC, in the past you've used both the M205 and the 85rd. Did you ever notice a significant diff between the resulting finishes?



Leaving aside Autopianism for a moment, not two people out of 100 would ever notice any difference between the finish, let alone on hard clear. Yeah, I've sometimes improved upon M205, but a) I can be nutty-extreme about this stuff, b) I really think you oughta think this one through for yourself, c) I firmly believe that you should try to *not* look for issues that you might not (really) have, and d) think you oughta keep in mind your other Qs regarding the overthinning of your clear; every polishing session takes off a little more and since you're repolishing as often as you are anyhow I wouldn't want to take off one iota more than absolutely necessary.



Since you've had the car for a dozen years or so, I take it this is a long-term commitment. I'd worry a lot less about ultimate gloss and a lot more about avoiding the need to polish every year.

You have a good point maybe I should just stick with paint work cleansers from now on. I do have Prima amigo but even that has some abrasives although very fine. Can you recomend a good cleanser?

This is how approach my '89 deVille with super hard clear. There's defects I've just lived with for a while now because the car's a keeper. Luckily, I haven't instilled any more of them, and haven't *needed* to polish in I don't know how long. The car is white, but my father has a red 'vette, that still has acid rain etching after a thorough sanding job shortly after he got it years ago. There's defects but the gloss is still out of this world and the car has won first and second place in shows, so I guess it's good enough.

What do you mean by sanding job?
 
The car had to be color sanded to reduce the severity of the acid rain marks. That made the clear even thinner. So now that it became thinner paint that was already difficult-to-polish-in-the-first-place,it wasn't a good idea for me to strive too hard to polish out all the light scratches and marring. It is at the point that you have to stand right on top of the car to still see some of the acid rain etching.

I don't recall now. I just recall from my research that it was a reaction to the EPA regulations that caused auto makers to change their paint systems. It was on some corvette forum.

On hard clear like that maybe Zaino's All-In-One. Or Klasse's All-In-One. I don't use dedicated paint cleaners much (generally preferring AIOs), though I did like Pinnacle's Paintwork Cleansing Lotion back in the day.



Flipping back and forth between this thread and the "semi-circular scratches" thread, I think you oughta sort that problem out first.
 
ZAIO looks great on Red, that would be my choice for maintenance as well. Then top with a wax of your choice or more Zaino if you want.

Zaino says that other products are not compatible with theirs what do you think of that?

While you do have to watch for "compatible with sealant" issues, generally it's not an issue and manufacturers just say that so keep you spending $ with them. I use all sorts of stuff over ZAIO with zero problems.

How do you like autoglym srp as an all in one?

I like it a lot! Gotta keep it off black plastic trim, and you gotta top it with something as it doesn't last long by itself, but it's good stuff IMO. Does a bit of filling too, so maybe it'd help cut down on that polishing I keep going on about ;)



It does have kinda a "signature look" that you may/may not like on your paricular paint, but the same can be said about most anything (if you look hard enough/care enough).

I do have it and its very bright and glassy I have applied it with pc should I continue with pc or by hand. Do you think the technology of srp is a little dated? Can I top it with Four Star polycharged sealant?
 
You should be good to go with M205 on that hard paint, but because M205 is abrasive/non-deminishing, I wouldn't use it for jeweling. 85rd or Ultrafina work good if you really gotta go beyond that.

Exactly. I discovered just that last time I polished my A4. Went 205, finished up with 85rd.
