On Mask/Bra & Paint finish

[RICO8458]

i plan on putting on a bra/front end mask. it is going to be rough to keep taking off and putting on except for a monthly car wash... question. what would be the best thick high protectorant wax or sealant to use in between the washing to protect the finish. i will keep it on in the rain, etc. snow,etc... would like to lay down a protection cover of some sort between the finish and vynil cover... thanks for advice mates.
