>>29094820fuck painting don't even bother. i'd gladly spend $5k than ever have to do it again.
>>29094820I got a little toaster oven and I’m trying to bake this Caliper paint I got so it’s harder. Had two layers, no primer. Flashed for 12 hours and now it’s baking. Started off at 100c for 15 min and now 150c for 30 min.
>>29094823Plating then?
>>29094820I just go to homedepot and buy 4 cans of spray paint whenever I want to change the color. It saves me a fortune
>>29094820I had decent luck with just regular old ceramic enamel engine paint so long as you choose solid colours.Every time I've tried metallic on calipers, including caliper specific paint, it seems a lot less resilient to and brake fluid exposure and tends to look bad faster. Gloss black, red, or green has done well for me.
>>29094850Have you used an oven to bake the paint? I found with my experiment of gold flake that if you bake it you can smack it with a wrench and even acetone didn’t dull it. It’s something to do with the bonds in the hardener getting much stronger than when air curing
>>29094820I'm trying to restore an old motorcycle frame. Scuffed all the old paint away to the bare metal and put some self etching primer on it. Should I still put high build primer on it? I do want a nice finish and the frame does need some smoothing out being a dirt bike frame from the 70s...
>>29097076Yes. Wait for the self etching primer to harden a bit and then use high build to fill in all the dimples from the acid. Then if you want a mirror smooth finish you can bother wet sanding it.
The problem with half this shit is that unless you have an actual dedicated spray booth setup or live in dry 30°c weather there is no reason why you'd ever want to do DIY painting. You would be better off doing a hack wrap job as that's at least reversible and protects the coat. Or if I wanted to do up wheels or small mechanical components and was desperate to do it at home I would powder coat instead of using standard automotive paint.Paying highschool educated wrenchlings at the local bodywork shop will always look better than doing it yourself, unless you're a highschool educated wrenchling with an inhouse spray booth.
recently picked up this front guard/fender for my commodore, looking to DIY fix the clearcoat patch missing. quoted too much from mobile guys , already have sandpaper and clear just wondering the best process
>>29097912Nice ride, same process as usual.Wet sand with 2000 and use a block, just do the edges and base coat patch where the clear coat lifted off and feather them into a smooth slope. Next tape off a rolled back piece of paper into a “C” shape so you don’t get a visible paint line at the perimeter and place the “C” 10-15 cm from the edge so you can feather it in better. Be aware that you will still have a little line which will be yellow/light gray where the new clear transitions to the old one, but there’s nothing you can do about that.
>>29097877kk thanks. I'm gonna throw a couple of layers of primer on it and sand it smooth. Then the paint coats, then finish with a couple of coats of 2k clear.
>>29097912>>29098108That all sounds good until:> you accidentally dig into the base paint as you are "smoothing it out"> the rest of the clearcoat peels off> as the new clearcoat dries and you sand it, you dig too far into the new clearcoatThis would literally be a multiple-day job for me to do "right". Fuck that.>>29094850How did you prep it and how many years do you think it will last?
>>29098147Chemically stripped the old caliper, then used a brass brush and cleaners to remove any surface rust. then soaked in in phosphoric acid to convert any invisible rust to iron phosphate. Etching engine primer + 2 coats of Detroit diesel green.I did my black and red s12 calipers the same way and they held up for about 10 years, though they did have some paint flake on the back of the caliper near the bleed screw.
