Grow + Seal in one operation???

Hello dear cleaning friends πŸ™‚ I am a newcomer and would like to have answered a few questions. This forum is really great and helpful !! Thanks in advance πŸ™‚ 1.) I have read that you can mix wax + seal and apply it to the varnish. Is that right or do you have to seal and then grow? 2.) Is the simple seal not enough? 3.) How long does a seal last? 4.) What is the difference between wax and seal??? 5.) Which products do you recommend? A The best ones seem to be 3M, SwizΓΆl, P21 and Zayno… is that right in the rough? Where do I get Zayno products? 6.) How often a year should one grow or seal? Drive about 12,000 km, no garage. 7.) What cloths or pads do I use to grow or seal??? Thank you very much for your kind help. πŸ™‚
