Been using the clear & back liquid tape from harbor freight (same as plastic dip I believe) for 2yrs lol
I told a person or 2 about it locally but they "prefer to use shoogoo.."
I spray 2\3 coats in front corners of my onroad cars and I can pretty much make 10+- racedays with out any cracks in the fenders . It has only added minimal weight (10g ish) but I bake all my bodies at 170 for 15 minutes to save about 5g.
