Questions about first polishing in life and 13 more questions

Hello dear forum, I’ve been ghosting on this forum for a long time and also read quite a lot of contributions to autopolitur. I still have to get rid of the fact that Celsi’s contributions motivated me to buy a Flex 3401 recently, with which I want to polish in the future. There was a contribution from Celsi, which I unfortunately can’t find anymore, where he wrote that you have to scroll up to 700,- EUR for a long-term polish. My car has these washing system scrapers (named the Swirls?), Some fingernail scrapers in the door handle pits, stone strokes (no big or disturbing) and very other fine scratches that I can’t match their origin. As a “tool” I now have a Flex 3401, various microfiber cloths, a polishing pad etc. As “polishing agent” I bought Meguiars SwirlX polish, Meguiars Ultimate Compund polish, Collinite Super DoubleCoat Wax (Carnauba base), Sonax Exenter polish 04-06 and a Sonax grinding paste. I have looked at some videos etc. and also read various posts in this forum. What I didn’t really understand: 1. Do you have to stick the car in partial areas, or is it only for orientation? 2. Can you also polish plastic parts (studs etc.) with the exenter machine, or are they basically polished by hand with other polishers, or do they also have to be “glued/covered”? 3. How do you proceed, compared to Is the SwirlX first used for my products, then the compound and finally the wax? 4. Do you have to wash the car again after every polishing step, e.g. Swirl polish, then compound, then the sealing etc., or do you apply the layers “over one another?” 5. Do my products even use the Flex 3401, or is there anything to consider? 6. I have also read that the polish agents are sometimes coarser, sometimes finer, what is the difference? 7. When do I take a Hard, when a soft pad, why do I have to pay attention to that at all and how long does a pad hold or how often can one use it, or how can one clean it properly? 8. Do all plastic parts (lights, trims, sliding roof seals, possibly bumper etc.) absolutely have to be glued off and if so, why? 9. How do one proceed with uneven areas with the machine (e.g. bonnet, which has different ups and downs) in order to reach any area? 10. Polishing the car with a microfiber cloth again dried by the polish residue? 11. I don’t have a garage or the like, can you polish it outdoors? 12. How do you polish places that cannot be reached with the Flex 3401, or are too small for it, e.g. at the back of the trunk or near the license plate? With your hand or does the “Profi” have a smaller machine for this? 13. Where do you start and where do you work? I think that the questions really have a good practice I have collected these questions in a period of about 2 months after I have looked at many contributions and videos, instructions etc.. I think that this could certainly answer the question of one or other beginner or interested person. Many videos or instructions presuppose a basic knowledge, even if this should be minimal, which I unfortunately cannot show at all in this part of my life. I also have curb scrapers on the rims, can I also use the above-mentioned products for my aluminium rims, or use a 3,000′ sandpaper to create an improvement in advance and cheaply?Since I also read a lot in the forum and some users almost had to apologize, because they had asked something, I ask for insight. Not everyone has to answer the above-mentioned questions, or point out any topics, or the board rules or tell me that I have the fingers there You too have started somewhere and had to ask the one or the other question. Otherwise I am really happy about helpful answers, for which I would be very grateful! Have a nice day and love greetings!
