Detailing cars and planes for …too long.
I DO NOT recommend use of any wax or ‘dressings’ (silicone).
Wax will last no more than two months and has a far greater chance of causing water spot damage. Dressings are just BAD.
I use a few ‘sealer’ which can last up to one year. Don’t expect any thing to last longer regardless of claim or price. My fav product for over 10 years now is Nu-Finish (orange bottle). Used as directed it will last a year. It is a cross link poly sealant w ability to condition surface. You will notice after one month (ap) water will no longer bead but will pull or separate and roll off.
You likely have an excellent buffing machine with your tools! The best is a dual action hand sander…gotta use
low profile 5.5 inch foam buf pads and you’ll have a PRO finish. I use ‘orange’ pad for 80% of work and some I do final coat with ‘blue or green’. I purchase on Autogeek.net which has very good detailing info.
Exterior rubber and plastics I luv Renew Protect (.com). These are dry seal products, one w black dye. I have had it last 6 months on tires and a full year on trim.
