i want to paint the grey trim on my Z71... it doesnt sound like i need the flex magilicutty... but maybe this bulldog jones you are talking about.
Originally i was planning on taking the trim off... sanding the crap out of it... using some kind of filler primer... sanding the crap out of it again... priming it and then painting as normal...
is this going to work or do you think this "bulldog" pre paint addative is the thing to use?
well im admittedly speaking primarily from anecdotal experience BUT.. if you have ever sprayed plastics and it kinda bubbles or clears out or repels paint.. those are specific instances of bulldog needs...
now to answer the real question...
They are plastic now.. so they do flex.. heat.. cold.. a door bumping it.. anything.. and down the road it will have spider cracks in it it might take a year.. it might now..
In my OPINION (and its just an opinion) if you do body filler over plastic or rubber.. it will crack.. if you paint it without bulldog it will basically be a single piece of paint , cured like a cover, hovering over a material it cant cling to.. and it will eventually fail... and if you dont use a flex additive it will crack as soon as the rubber does its job and flexes at all
scuff it.. bulldog it.. flex additives.. no body filler and plan on it lasting a long ass time....
changing any of those things will not nessacarily ruin it.. just increase risk.
