Last time you killed it, how did it bead during the pre spray? Was it already flat then?

If it really is dead in 3 days no matter how you try to do the application, you should contact optimum and see if you got a bad bottle. No way a 1 yr sealant is going to last only 3 days and be dead in the first wash unless it’s defective.

You should skip the polish since you already polished recently. If your wipe down has trouble ridding all the residue from polishing oils, you’ll be back in the same situation as before. I’m not convinced most panel prep can clean all that well. Do you see it beading on the surface of the paint...

Why don’t you just test all your products on your similarly prepared hood to see. Then you’ll have a side by side to know it it can outlast your other products. A 1 year product lasting 3 days certainly sounds like either your prepped incorrectly or you got a bad bottle. But it is always...

One thing I noticed about wowa sealants is that they also need a good cure time before allowing any moisture to touch them including evening dew. Some of those spray and wipe sealants may not be as sensitive. But Ultima PGP (and likely optiseal) I found were very sensitive. If you let it cure 24...

I’ve had optiseal last 6 months so 3 weeks seems like a bad bond to me. Since you’ve already polished, why not wash it a few times with your optimum car wash, then use gyeon prep again, then apply hyper polish like a wowa, and leave it alone, dry, and untouched for 24 hours other than initial...

What polish did you use? Could have left lots of oils behind which Gyeon prep did not remove. Also, did you apply a lot (liberally wet the whole surface) of Gyeon prep and let it dwell? You need to make sure you are getting all polishing oils off. A one year sealant shouldn’t last 2 days. The...

Did you keep the car dry for 24 hours after application and before you attempted to wet it to test beading and wash it?

Those are for Alcantara so unlikely the right product. But if anyone has those and wants to give it a try and let us know….at least we would have some data point.

Something that seems to be a prevalent problem, seems to have lots of discussion on how to handle it after it's failed, but not how to prevent it. This problem is the degradation of soft touch surfaces that are on lots of European cars, including Ferrari, Maserati, VW, MB, etc... who use this...

Just wondering if anyone who tried optilens, especially those in this thread, have longer term results of it protecting/failing on new and re-polished headlights. It's been quite a few years since the last post. I'm especially interested in the ones that seemed to have good results so far in...

I'm not sure if it was related to ash, but I have a 2018 yaris which has a headlight where the top has lost it's coating in a pattern that looks like how water would sit on it if it rained. I'm in norcal so had that ash on it for a month where I didn't wash it since it was terrible air all the...

Any IEM (shure, etymotics, westone, ultimate ears, klipsch, etc...) is going to do well for use when detailing. They isolate noise well so they're like wearing earplugs when you have your polisher going. You also get better sound quality (with a good model) than any over the ear headphone...

A few questions I hope Drew or someone who knows could answer. - What happened to the machine application video? It says video not found. - Is using a qd or waterless wash for removal going to affect durability or beading quality? The hand application video mentions removal without a qd to...

I hate it when trying to drive on a fwy that is relatively empty using cruise control and the guy in front of you can't keep a constant speed. I then have to keep adjusting the cruise control up and down just to keep a good relative distance to the car in front sometimes even have to tap the...
