HI folks

I have a white Ford Focus LX, which is not garaged and has to suffer through the extreme UV radiation of a Perth summer. To do the best for the car's protection, I bought some Collinite 476S and 845.

I washed and claybarred before applying 2 layers of Collinite 476S. I intend to apply one more coat of 476S before finishing off with an application of Collinite 845 (which I understand is especially designed to afford UV protection).

My questions:
1. Should I claybar again before applying the 845, or will this remove the current layers of 476S? Or, is it simply unnecessary, since I used the claybar within the last two weeks, and immediately after applied the 476S? (For the second application, I only washed and dried the car - didn't claybar - and was intending only to wash and dry before applying the last coating of 476S).

2. How long after the application of the final coating of 476S should I wait before washing the car again and applying the 845?

3. Is there anything to be gained by applying a second coat of 845 soon after the first? If so, I assume I don't need to claybar, and do need to wash and dry immediately beforehand, as with the 476S?

Look forward to some advice from folk who are more informed on this stuff than I am - that throws it wide open!

Cheers
 
No, you don't need to clay again, unless you have some sort of extraordinary fallout that has already pierced your 476. 845 is essentially "watered-down" 476, so I don't think you have anything to gain by topping the 476 with it, and it will probably remove some of your 476 due to the higher solvent content of 845.

Claying after applying the wax will remove it so I'd say not to.

Washing with a recommended car wash detergent is fine the next day. Other than boosting the gloss already there I don't know if adding more will help.

Washing the finish before applying anything is always recommended otherwise you'll risk the chance of damaging the finish...
 
:iagree:With Bobby.

Two coats of 476 or 845 should be all that you need. Nothing else is required. More is going to be overkill and waste of product.
If you have had success in applying thin layers of 476, stick with it. You may also want to search out the various links on 845 and how we use it/apply. There is alot of information available.
You may also want to look into using the Duragloss line of products. Collinite and Duragloss are a hard combo to beat.

Also, Welcome to Autogeek. :buffing:
 
any pics of the car?

If it's outside all the time, I'd be more concerned about cleaning the paint throughly before sealing in all the contaminants with wax.

Did you polish the car first or use a paint cleaner after the claybar step? Since it's white, you might also want to consider adding Iron X to your process.

wash
dry
iron x
rinse
claybar
polish/pre wax cleanser
wax

I agree that 2 coats of 476s is more than enough protection.
 
Welcome to AG first of all.

As mentioned 2 coats of either wax are more then enough .. indeed.
 
Thanks very much, folks - your comments noted and much appreciated.

Seems like I may have been misinformed on finishing off with a layer of 845. My understanding was that the 845 is especially formulated to resist UV light and heat, which I thought was exactly what was called for in my car's ungaraged exposed-to-extreme-summer-sun situation.

But if the solvents in the 845 are going to strip the 476S, I'm obviously better off with the two layers of 476 I have just applied.

And yeah, I did clean the car thoroughly before using the claybar and 476. I used a bit of cheap and nasty Kitten liquid cut and polish after a good wash with Armorall carwash liquid. The Kitten was bought long ago, before I even heard of top-end products like the Collinite waxes. It did seem to do a good job, though, getting rid of stubborn marks and bringing out the shine.

Just one more question, pls. I'll be away for a month, and was intending to put a car cover on the car during this time. It will be in the sun, relieved only by a bit of temporary dappled shade from a neighbour's overhanging shrub for part of the day. The wax won't melt or bond to the car cover, I trust?

Cheers!
 
There's probably not a more durable wax available than Collinite. I've never had a problem with a good cloth car cover.

Guys, just one more question, pls. Should you use the 476S and/or 845 on the plastic sections of a car (eg: my Focus has plastic bumpers)? I have done so, and it looks fine, but just wondering what the expert detailers do...
 
I prefer using wax on any surface of the car that will accept it without any issues. Waxes won't darken faded trim like some of the dedicated vinyl protectants / dressings, but the durability is just so much better (think months rather than weeks) and there are no issues with runoff streaks. You just have to be careful where you go. Put some durable wax on the wrong surface and it will be a real pain to remove. Test spots are mandatory when you're venturing outside the norms.

I've used 845 on textured black trim with no issues, applied in a wipe-on, wipe-off fashion. Pretty good looks, does not does not run in the rain, and it'll have that same vaunted 845 durability. In fact, there's a thread on Autopia.org with a long-term test of 845 and a number of trim dressings, with very impressive results for 845 (not sure it's ok to post a link, just do a search for "Product Testing - Trim: Adams, Optimum, Collinite, BlackWow").
 
I always go over the smooth and textured black trim when I use a wax like Collinite (476S or 845) or #16.
 
Guys, back again a year later. The two coats of Collinite 476 lasted about 7 or 8 months. I should have applied some more long ago, but have been slack. Anyway, finally got on to it today: washed and claybarred the car, but ran out of daylight, so will apply the 467 tomorrow evening.

Quick question, pls. Although the claybar has left the surface of the car slippery smooth, viewed in revealing light it is quite obvious that the finish is not great - lots of swirls, water-like marks, smears, motley patches etc.

Last year, as described earlier in this thread, I resorted to using some Kitten cut and polish wax to even out the finish before applying the 476S. Cheap and nasty perhaps, but the Kitten did a good job. However, I'm loathe to use it again now. It was already old and it's a year down the track. Plus I suspect that there are less abrasive products than cut and polish these days that will take off the smears etc and produce just as good a finish.

Can anyone recommend a good quality polish that won't harm the car as cut and polish might, but will get the smears off and buff up to a great finish prior to my applying two coats of 476? Would be much obliged.

Cheers!

There are lots of products that will fill your need, but the ones I use the most are DuraGloss 501 and Meg's D151. The DG is IMO less aggressive than the D151, but its ability to clean the surface is outstanding.

Thanks for your recommendations, BillyJack. Unfortunately, I can't get either of those products here - at least, not from any of the car-care specialist stores in my area.

I can get Meguiar's Ultimate Polish and Ultimate Compound. I was thinking of using the former, and if that does the job, just cleaning it off and applying the 476 to finish. Do you think that sounds like a reasonable strategy?

Cheers!

Both are excellent products. Your plan to start with the least aggressive polish first is sound, then if that doesn't do it, go for the ultimate compound.
 
Thanks, steamshooter! Feel confident I'm doing the right thing now.

Cheers
