it will be ok you dont have toput something to handle heat you dont even have to strip the old paint just clean it really good then spray it twice tell it drys then 2 more times after that it will be fine... after the paint warms up it will bake on there and will look really shiny and great just buy alot of those cans and dont mess up but most importantly clean it really good id say with carb and choke cleaner or paint thinner!!!!
