The special polymers in our Hybrid Wax sometimes don't work well when applied over typical car waxes and sealants unless it's a full polymer based product such as our CarGuys Liquid Wax.
The other main reason that could cause streaks is over-application. This product is unlike any others on the market, it's very concentrated, it doesn't contain any unnecessary fillers such as coloring, scents or fragrances, so very little is needed when using.
Over application will lead to streak so you need to make sure you're only using 1 spray per 2 x 2' section.
When applying the best method to do this would be to:
1) Make sure surface is completely dry
2) Apply Hybrid Wax (1 spray). This can be sprayed onto every surface on your vehicle from the glass, paint, metals, plastics, decals, clear-bra, fiberglass, and more. There are no limits to it!
4) Do 1 quick wipe/buff with the microfiber towel, if you see a bit of residue, let it sit for about 1-2 minutes to dry, then go back and do a final buff. This should get rid off all remaining residue.
If you are still seeing streaks and wondering why they are not going away, simply buff off dry and try spraying a smaller amount than what you have been doing (1/4 trigger pull) and follow the same steps by wiping it off once, then letting the remaining residue dry 1-2 minutes before doing the final wipe down.
Having said that, all our products are backed with a Zero Risk 100% Satisfaction Guarantee policy. Let me know if that is something you would like to pursue.
