After epoxy on sand blasted metal I used UP2253 for high build. I like it because it is a DTM primer (High Build, Surfacer, Sealer) depending on how much it is reduced. Day of paint I use the same product 4:1:2 as a sealer. I STRONGLY advice a wet-on-wet sealer coat. It provides a uniform surface, covers any bare metal burn throughs, and lays super flat. Put it on just like it is the first coat of base, flash 15 min or so, and then apply the base. I used Sunfire PRO Premium for the base and Finish 1 (FC720) clear. I really like both the bc and the cc products. I bought 1 gallon of Ready to Shoot base and then went and got 1 additional ready to shoot quart. I ended up reshooting the grill and still have the four fender flares to do. But when done I'll likely have that extra quart left over. Just didn't want to run short. Nothing worse than running out of base at the very end when you need one more coat. I bought 2 gallons of clear. You can easily do the entire bronco with 1 gallon of clear if your doing 2 coats. But I spray 2 or 3 coats, let it set a week, block it flat with 800-1000, and then reshoot another 3 coats. It looks amazing at that point but I then cut 1000, 1500, 2000 then buff first with wool pad and then three step foam on a rotary. I have enough clear on it to really flatten it when cutting and don't worry too much about burn throughs, although I still avoid edges. The top is done last and it will be sprayed in SS white with 2 coats of clear for light cut and buff. Overall all the paint (epoxy, primers, bc/cc) cost about 2k.
The plastic is just 3m pre-taped masking roles. easy to use to mask off large areas.
Geez, just typing that made me tired remembering all the work it takes to prep the body for paint. Don't even ask how many hours of metal cutting, welding, blocking...but hey, its a hobby for this old retired guy and I love doing it. Once its done it will hopefully go to a new owner who appreciates it and I'll find another one to do
