chanlon1 Posted March 18, 2019 Report Share Posted March 18, 2019 Removed the calipers over the weekend and brushed them down. Washed them with paint prep wipes and brake cleaner. Sprayed the caliper paint on, and did many fine coats, however there were always a few spots that didn't see to want to take the paint.....it seemed like the paint physically wouldn't stay on. I've circled these in the below photo. Any ideas? Should I just mask off the area, sand it down a bit and respray? Or do I sand the whole caliper down again and start from scratch? I'm trying the next caliper with a different brand of spray incase there was something strange going on. Other than those marks, they seem to have come out okay, just need to apply the decals........

Lonewolfgjp Posted March 18, 2019 Report Share Posted March 18, 2019 Hi there Its normally grease/silicone that causes these types of problems. I think I sand the problem spots and put a bit of primer on them. Give them a light sand again and dust some red over the freshly primed spots. The primer should help stop the reaction 👍 Link to comment Share on other sites More sharing options...
T911UK Posted March 19, 2019 Report Share Posted March 19, 2019 If they are just anodised from factory as some black ones are (cant see to well so maybe yours are) then you normally need a decent etch primer first, you cant just spray top coat on and expect it to stick or not react a little.

chanlon1 Posted March 19, 2019 Author Report Share Posted March 19, 2019 Thanks. I’ll try sanding down the small area and adding some primer. The paint stated that primer wasn’t needed, hence the reason I didn’t use any. Link to comment Share on other sites More sharing options...

Patt Posted March 19, 2019 Report Share Posted March 19, 2019 I always dust the sandpaper over (ensure decal fully gone), wipe down with brake cleaner then etch prime before painting them. Link to comment Share on other sites More sharing options...
chanlon1 Posted March 19, 2019 Author Report Share Posted March 19, 2019 I’ll be trying some etch primer later on the spots. Link to comment Share on other sites More sharing options...
Jason986S Posted March 19, 2019 Report Share Posted March 19, 2019 I would always primer first myself Link to comment Share on other sites More sharing options...
chanlon1 Posted March 22, 2019 Author Report Share Posted March 22, 2019 Update. I sanded down the little spots mentioned above. Primed them and respirated. Unfortunately you can see the difference in thickness where I sanded. Ended up wirebrushing the whole caliper again. Will be spraying primer over it this morning and starting again! The other caliper seems to be okay. Thanks for the suggestions so far. Colin. Link to comment Share on other sites More sharing options...
chanlon1 Posted March 22, 2019 Author Report Share Posted March 22, 2019 Its not 100% perfect but way better than it was. Doesnt have any laquer on it....should I? Link to comment Share on other sites More sharing options...
Lonewolfgjp Posted March 22, 2019 Report Share Posted March 22, 2019 I think considering how bad they were they have come out well. I have only ever repainted calipers that have been originally red so I’ve never had to etch primer. I tend to put a coat of lacquer over even if the red paint I’ve used says you don’t need it. I find they stay glossier for longer with the extra coat of lacquer. You haven’t got to go crazy, just a couple of light coats will do it 👍 Link to comment Share on other sites More sharing options...
chanlon1 Posted March 23, 2019 Author Report Share Posted March 23, 2019 I thought I’d test the laquer first in case it went t*ts up and ruined everything. Anyone for a fancy lacquered spanner..... Link to comment Share on other sites More sharing options...
chanlon1 Posted March 25, 2019 Author Report Share Posted March 25, 2019 So I eventually got one caliper done and lacquered and back on the car again. Only 3 more to do, before I even go near bleeding them....... Before and after shots: Link to comment Share on other sites More sharing options...
Nobbie Posted March 25, 2019 Report Share Posted March 25, 2019 Lovely job😎, any slight imperfections you notice while spraying will be lost when on the car. I made a right pigs ear of my fronts with paint reactions etc, but they still looked good unless you were on your knees peering through the wheels at them😀 Link to comment Share on other sites More sharing options...

Out of interest, did you lacquer over the top of the stickers or just stick the stickers on and leave them? Link to comment Share on other sites More sharing options...

I tested the lacquer on a spanner and sacrificed one of the decals as a "test subject" ..... there wasn't any reactions etc Link to comment Share on other sites More sharing options...

the baron Posted April 13, 2019 Report Share Posted April 13, 2019 Lacquer will keep the stickers in place and not degrade over time, i sprayed mine up, black with white decals but did it in situ, as others have said any imperfections really wont be obvious when on the car behind the wheel.
