Mysterious Black Sling

[subjectzero]

Ok so I love using the purple grape koolaid smelling tire shine from Meguiars. I like how it lasts more that 3 days. Now I've been racking my brain trying to figure out where this black sling is coming from. It seems everytime I detail my car it shows up the next day. It looks like I drove through wet asphault. and it gets slung all down the side of my car. I've noticed it on the tires really bad when I apply the shine. Its spotting up on my rims too. Nothing a car wash can't cure but its a real pain to deal with. I usually don't budge the car until the next day so the shine should be dry. I'm wondering where its coming from. I can assume that the shine is not drying right which is flinging everywhere when I drive. Plus I don't get the shine I normally get. I just can't understand where this gunk came from in the first place. Any takers? What tire cleaner should I try out to clean this stuff off my tires? There's different ones and I'm not sure which would be best for this situation. I'll try and get a pic up tomorrow.

Re: Mysterious Black Sling

Sounds like you are putting on to heavy of an application of your favorite tire shine. Even though you are letting it dry over night, it still wont stick because it dosent have a clean surface to adhere to. Next time you wash the car, use a nylon brush and thoroughly scrub the sidewall and let dry before applying the shine.
When applying the shine, just a nice even coating is all that is needed. Repeat everytime vehicle is washed.

Sounds like you are using way too much product. Use less product, after you apply the product. Wait 20-30 minutes and wipe off any excess product. This should greatly reduce if not eliminate the tire sling of product.

I echo the advice already given - clean the tire properly with a good APC (all purpose cleaner) and ensure that the surface is dry before applying your preferred dressing. Apply the dressing in a thin, even coating and let it dry - it's better to apply two thin applications than one generous application. Wipe off any excess, especially that which builds up around lettering and other patterns on the sidewall.

Remember - wet product + physics of motion will always result in sling.

The guys who have chimed in on this so far are spot on. Especially with a gel type product like Endurance, a heavy application is going to sling off even if you let it sit for a day or so. The problem usually stems from the graphics and textures present on many tire sidewalls these days; they tend to hold just enough product until the tires hit a certain speed and then physics takes over and finally dislodges it.

The trick is to clean the tires thoroughly first using a good all purpose cleaner and a tire brush, then applying any product in a thin coat and wiping off any excess after a few minutes. Pay careful attention to the graphics and textured areas of the sidewall - an old terry cloth towel works great for this. Apply a second thin coat if you want to bump up the gloss a bit.

When the new trigger spray version of Endurance comes out this problem will be pretty much eliminated since it will dry completely dry to the touch in a matter of minutes. Now, that's not going to be license to just glob it on, so don't go crazy with it!

Re: Mysterious Black Sling

Yup you guys were right. I had been washing the car at home so the tires weren't getting that pressure wash to remove all the grime and previous applications.
