I have thought about it, and I think I will go straight to PPF without applying any liquid. The reason is because, in the future event where I will need to remove the film and reapply new film, I do not want to be sanding and polishing again. In that event I would want to easily just clean the lens and maybe just do 1 round with the black polishing pad and go to film quickly.
The liquid is a black box for me, I have no idea how it will behave under the film... it may degrade quickly, it may expel gases that degrade the film or create air bubbles or mess up the look of the film and in these situations I do not want to go through this ordeal again even though I am better at dealing with it now.
I could just go with the liquid and forget about applying the film... but again the liquid is an unknown to me. How long will it last? Really I do not want to touch these headlights for another decade if possible.
Your ideas?
BTW: as stated here:

1) get the headlamp polish kit from MrDIY - visbella brand
2) do everything as in that polish kit. However do not do the last step. Their UV applicator is not good quality as it will not last long.
3) get meguairs or 3m headlight protectant (can easily find in Shopee or buy from Acehardware)
4) use the good quality headlight protectant for the finishing step. This will ensure the headlight last for long time.
