Resealing the roof on my ws31 Quantum

[quantum]

I want to lap seal all the seals, vents, ac, antenna areas. Also where the front and the roof meets all the way around to the rear.

I have the single cover, not rubber roof, and want to use a self leveling and a good one that will look good and do the job.

My question is:
--Is there a lap sealer specific to adhere to fiberglass as well as the existing seals.

--Or should I remove all the original factory putty seals and re-do them from the get go.

I have watched video and they say clean the old areas well, use a high grade sealant/self leveling lap sealer and all will last a long time.

I am in good shape now so with some upkeep now I feel I can keep the original seals in place and do a quality over seal

Any one been this route

Thanks
