Oh that sux.... I would suggest getting a car cover .... I know you probably dont want to rake out the dollars but if you wanna protect ya baby from unwanted scars...it will be a good investment.
Also I know bleach turns cats away, I have used it before in the garbage bin when its full of trash and the lid cant close... and came out the next day and garbage was never touched....
I would also suggest the Daisy Red Ryder BB Gun with a compass stock... but you might shoot ya eye out "A Christmans Story" Great!!
