Re: blending clear coat... help

Use 1000 or 1500 grit depending on what color you are blending, for light metallics I usually go with 1500 so the metallics don't stand up in the blend. Look for the narrowest area to blend the clear in. Sand almost up to the area you want to clear to go out to and then use some compound on a rag by hand and rub over the area where the clear blend will be at. Step the clear out with each coat so the edge doesn't get to thick. After the last coat is starting to get stringy try to melt in the edges. I have been using some U-pol fade out spray in a spray can to melt the clear edge in and it seems to work well. I'm sure Sikkens probably has a similar or better product, I know Lesonal has one but I forgot what it's called. After you are finished and it's dry you might have to polish the blend by hand to get the shine up. Try not to use a buffer because it can peel back the clear in the blend.

I agree this is not the right way to fix anything. I got into doing some car lot spot in work at my shop until the customer started thinking this was the only way to fix something. The day they wanted me to spot in the front fender of a late model Rolls was my last job I did for them.

Re: blending clear coat... help

Your right,not the best way but you have to do it some times.Good advice given on previous post.Basically you are doing the same thing as a sail panel blend.Make sure the bumper is clean and no bug guts.If you are in a hurry you can use a gray or gold scotchbrite pad or some norton foam backed sandpaper in 800 grit.just remember not to clear past where you scuffed,sikkens sra is what we use to melt the clear,sikkens paint system as well.From what I have heard wanda is the cheapest paint line akzo nobel has,maybe that says something about the shop too.

Re: blending clear coat... help

When i used to work at Russel BMW, we just used this soap-like goo with a fine sand in it and a sponge. scrub the panels down, wipe clean, bam! no shine, very fine scratches! off to the booth!

Re: blending clear coat... help

I've actually got some similiar issues...

When I sprayed the roof for my vinyl top for some reason the adhesive ran down over the clear, I am a slob I guess...removing the clear and some paint...I have sinced touched up the paint with a paintbrush but am wanting to know a few things...

1. The adhesive removed the base down to the primer in a few spots. I filled them back in with a paint brush pretty thick. Can I sand the base with something to make it all smooth?
a.) If I sand the base and it all looks smooth then what? Reshoot it color or clear it???

2. What should I do about blending the clear? This is a very looked at spot. Its not in a place that wont get noticed. Should I use a blending technique or just 1200-1500 the clear and shoot the whole panel again???

3.) What exactly is U-Pol Fade?

Huge pics are here...

My gallery is looking a little sloppy as there are many more pictures to add but I corrupted the data base so now in my free time I am rebuilding it...hope the pics arent a problem for any of you...

THANK YOU !

From the look in those pictures, those quarters need to be resprayed to look right. You can't touch that up with a brush and get it looking good.

67 GTO more Chevelle than Pontiac.

Re: blending clear coat... help

if you look at them closely you can see where the clear has come off and there's actually a line there... There are also little chuncks that I haven't taken off yet.

Should I rough up the clear and repaint the whole quarter? Its ONLY the drivers side that did this...Thank goodness.

Re: blending clear coat... help

Will respraying clear over clear cause it to lift later?

Not if it's sanded and prepped correctly, it won't.
