Guys help please?

Re: Deep Crystal with a G220 & paint depths.

How bad are the defects and what level of correction are you trying to get ( 90 to 100% defect free for example)

Ive used DC1 many times before, its very mild and will barely remove any defects. You should try Swirl X first and then UC if you need it.

IMO, You should definitely apply by hand on the areas that have 80 - 100 microns of paint, Its better to achieve some correction instead of having a spot with no paint ( even though I don't think you'll burn through the paint with DA and even UC )

The only benefit that I found when applying wax with the Porter cable was that it was quicker, nothing else really

With all that said, I would still wait for someone with more experience than me to chime in , just wanted to give you my opinion. Good luck!

Re: Deep Crystal with a G220 & paint depths.

Great, thanks for your reply.

I guessed dc01 was very mild. I would imagine using a d/a will improve the cut?.

I have seen many people use u/c straight away and blind without using a paint depth gauge.

So either I use u/c and limit the passes on thinner paint areas say 2- 4 passes/reduce speed on the d/a to 3-4. Or use u/c by hand.

And where the paint is thicker 4-6 passes. With the speed on the d/a 5-6.

Any more hints and tips guys?

Guys and help please?

Re: Deep Crystal with a G220 & paint depths.

I have just purchased swirl x. So now I have range going from U/c down to dc01.

Can I use dc01 for very fine swirls/scratches with a d/a? or am i wasting my time?

Rappy.

Re: Deep Crystal with a G220 & paint depths.

The main areas with the paint thickness up to 170 microns shouldn't present any issues for you at all. But those problems areas do indeed show very thin paint and caution should indeed be used.

SwirlX is very mild, especially when worked by hand, so we don't anticipate you running into any problems with it. If you're still a bit unsure about this, by all means try using DC1 via D/A there first. Obviously you can vary the cut of any liquid by using a more or less aggressive pad, using a higher or lower speed on the D/A and by using more or less pressure.

Paint sensitivity is going to play a large role in this process too. But it sure sounds like you already have a pretty good idea what you're dealing with here and that you know to proceed according to the thickness of the paint. It's pretty obvious from the questions you pose and the background you've given that you aren't a total newbie who's jumping into this blindly, and that's great. Just use common sense, start very gently in those thin areas, and slowly increase the overall power you put into correcting those areas.

But for the thicker areas, even SwirlX on a D/A should cause no problems for you. UC should be fine as well, depending on how responsive the paint is.

Re: Deep Crystal with a G220 & paint depths.

Thanks for the comments/reply.

Just curious on hard to reach areas say below headlights where the area to work is less than the pad area. Do you still use a d/a or by hand?

The same applies around door handles? I may be answering my own question here. I would imagine some work by hand will be required. Use a d/a up to these areas with caution.

I'm not a complete novice thats true, but I want learn more with using a d/a. I'm aware that a d/a will cut far quicker than by hand.

What paint depth would you say is a no no with a compound?

If I get very thin paint I think I would use dc01 on a slow speed say 2-3 and keep checking the depths.Does that sound right?

Also I will vary the passes from 4-6 depending on paint depths etc...

Re: Deep Crystal with a G220 & paint depths.

When using a D/A you rarely need to worry about removing too much paint, unless you're working on very, very soft paint that is quite thin - we see this most commonly on old, original single stage paint systems, classic cars, etc. Even using something like Ultimate Compound with a polishing pad on speed 5 (assuming Meguiar's G110v2, Porter Cable 7424 or similar tool) it's rare that you can measure any real difference in paint thickness after buffing. A lot of what's happening is the rounding off of sharp edges from the swirl marks, which stops the harsh reflecting of light from the surface. Basically you remove the prism effect of a sharp cut in the clear coat when doing this. Obviously in areas where you know the paint to be very thin it's wise to proceed with caution, and you plan sounds excellent.

As for hand work in tight areas, sometimes that is indeed the only option. You don't need to move to hand work just because an area is smaller than the pad diameter, though. A-pillars are a case in point; though much narrower than the diameter of a typical D/A pad you can still effectively work on them with a full sized pad. You can usually work on the tops of bumpers quite easily as well, but of course each vehicle is unique so common sense will dictate what can or can not be machine corrected.

Re: Deep Crystal with a G220 & paint depths.

Thanks for your sound advise I appreciate it

The last time I used a machine was around 15yrs ago and it was a rotary with a lambs wool head and t cut on full speed not sure of thr rpms now.If only I knew then what I know now!!!! You can see where this going

basically my bonnet needed a respray.

I have a g220 basically thats the uk version I'm lead to believe. The d/a sounds a fine tool from what you have been saying. I would of thought that my paint gauge would show a before and after reading.

Heres some pic's of my VW

. Ref to applying by hand. Below the headlight of my passat there is a slight ridge can I use the da there. The reason I ask is because the pad will not be sitting flat as its a curved surface. Hope that makes sense.

Well, the Meguiar's G220 is the same tool as our G110 D/A with the only difference being that it's made to run on 220v current rather than the typical 110v current found in the US. Otherwise, it's the same tool - the one we've been describing - so you should be good to go. While not totally impossible to do any paint damage with this tool, it is not impossible. But you would have to do something extremely aggressive with it to cause problems, and from the sound of your posts you don't strike us as someone who just throws caution to the wind and jumps in blindly. We think you'll be just fine.

Even though the pad won't be sitting totally flat in that area, and that the area is smaller in width than the pad is in diameter, you can still use a full sized pad there. Sure, it will cantilever off the edge, but that's not really a problem. The pad and tool are actually quite forgiving in these areas, just take your time.

You may well find the paint on this car to be fairly hard (ie, difficult to correct) as you work on it. Many VWs are known for their hard paint - not all, but it is quite common to find hard paint on VW vehicles, so just be prepared for that. All it means is that you may need a couple of extra passes to correct the defects, or a more aggressive liquid (ie, Ultimate Compound instead of SwirlX). But keep in mind, too, that if you are not removing find swirl marks then you really aren't removing any paint. This is true in the areas of very thin paint and the more robust areas as well.

Re: Deep Crystal with a G220 & paint depths.

Just curious when is the release date for Gold class plus carnauba in th uk? Also any new products beinging launched this year?

Thanks.

Re: Deep Crystal with a G220 & paint depths.

Not sure exactly when you'll be seeing Gold Class Carnauba Plus - you might want to contact the guys at Meguiar's UK for that info.

New products for 2011???? Hmmm....... probably.

Check back the first week of November during SEMA week. We just might have a thing or two then.
