Snoozin Posted October 17, 2011 Share Posted October 17, 2011 I have a number of small pieces for the KP I want to paint, and I want them all to last. Stuff like headlight bowls, brackets, stays etc. What is the most reliable/durable method of doing this while remaining somewhat cost effective? I have a small air compressor which I think would be up to the task of this sort of thing. I'm not after super shiny SEMA winning finishes, I was more thinking along the lines of satin black for all this stuff. But I want it to last. So what kind of paints, gun, and how should I use it all? Or alternatively should I just be using rattle cans? My experience with them isn't flash though, really (although impatience probably has a lot to do with it). Idea me!!! Quote Link to comment Share on other sites More sharing options...
two_days_late Posted October 17, 2011 Share Posted October 17, 2011 That "Hammerite" paint is meant to be really good. Have just painted up my suspension etc with it and its meant to extremely durable. Can get it in spray cans or tins. Cheers Matt Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted October 17, 2011 Share Posted October 17, 2011 wattl killrust paints are a really strong spray can paint, can sometimes give a bit of an hammer finish and sometimes not, unsure if that's just my technique/what im painting or they actual paint. powder coating can sometimes be pretty cheap if the painters are already spraying that colour too edit: that post above reminds me you can also get killrust in a tin too Quote Link to comment Share on other sites More sharing options...
tortron Posted October 17, 2011 Share Posted October 17, 2011 paintbrush it on both killrust and por15 will self level pretty well - i.e no brush strokes Quote Link to comment Share on other sites More sharing options...
Jase Posted October 17, 2011 Share Posted October 17, 2011 cost effective you say, rattle cans in a bucket of hot water, clothesline on a hot day, or just strip and blast them and have them zinc dipped (cost me $50 to do two fishbins of stuff a few years back) Quote Link to comment Share on other sites More sharing options...
Unclejake Posted October 17, 2011 Share Posted October 17, 2011 I have tried them all. Hammerite chips off suspension parts, but was awesome on my engine block. POR15 brushed on is a great option. Do that. Quote Link to comment Share on other sites More sharing options...
xsspeed Posted October 17, 2011 Share Posted October 17, 2011 From memory por15 is not "uv stabilised" - according to their datasheets at least - and they suggest using one of their other products (chassis black?) for things that won't get a top coat of some other paint. (This is all IIRC as I read it, and not from practicle experience which UJ clearly has) Quote Link to comment Share on other sites More sharing options...
tortron Posted October 17, 2011 Share Posted October 17, 2011 ^ will lose its gloss if left in the sun. wont fall off tho Quote Link to comment Share on other sites More sharing options...
keefs86 Posted October 17, 2011 Share Posted October 17, 2011 used killrust on the insides of the doors of my car, should be good, contains rust inhibitors so should stop all the badness from happening. great finish from a rattlecan. Good and glossy, exactly what the inside of a door needs.....unseen beauty. Quote Link to comment Share on other sites More sharing options...
Unclejake Posted October 17, 2011 Share Posted October 17, 2011 From memory por15 is not "uv stabilised" 100% true. I got the impression that Richie was painting stuff that would live out of the sun though, but he didn't actually say so i could be giving yet more bad advice. Also: If you purchase a can of POR15 you must also purchase a small roll of Gladwrap to place between the tin and the lid errtime you use the paint. The bestest spraycan of etch seems to be the Wattyl product. It adheres an gazzionion times better than CRC Zinc-It. Yes. An gazzionion times better. I counted.

bubblegoose Posted October 17, 2011 Share Posted October 17, 2011 crc zinc paint is more for covering repairs to farm spec welds and shit but the crc black zinc is pretty good tbh and comes in spraybombs and tins you can use your compressor with too brunox is pretty dope for priming bare metal but runs heaps, stops rust and has an epoxy primer all in one tin Quote Link to comment Share on other sites More sharing options...
phtmbl Posted October 17, 2011 Share Posted October 17, 2011 Paint is paint, POR and Hammer Rite are great but if you do not strip,sand and primer and so forth nothing will stick for very long. Quote Link to comment Share on other sites More sharing options...

BlownCorona Posted October 17, 2011 Share Posted October 17, 2011 was sold on killrust one i tightened my wheel nuts on it and it didn't so much as scratch. Quote Link to comment Share on other sites More sharing options...
slacker.cam Posted October 17, 2011 Share Posted October 17, 2011 If you have a compressor you can borrow a spray gun (assuming you don't already have one) and paint them properly. A little compressor is fine for brackets and stuff. All of the bumper mounts and stuff like that on my Silvia were sandblasted to bare metal and then etch primed with a PPG product (can't remember the code right now) and then a hit with a 2 pot gloss black. 3 years later they still look as good as the day I painted them. IMO this is the 'best' way to deal with things like this. Rattle cans are just much less durable. You can buy small tins of decent quality paints so it doesn't have to cost a squillion dollars. There's always a tradeoff between how much dicking around is required and how long the finish will last though. If the parts will have stones and stuff hitting them then this wont be the best way to go. If you have suspension components and whatnot then I'd reccomend spraying thinned down POR15 or powder coating. I say spraying the POR15 cos it's not really much more work than brushing it on and it's actually quite a pleasure to use when it's thinned down properly. It will give you a gloss finish.

Snoozin Posted October 17, 2011 Author Share Posted October 17, 2011 Sweet thanks for the replies. The few undercar bits and the diff I need to do, I'll do in POR15, this is a given (and I've already had a bunch of parts powdercoated... doh) but the other pieces that I want to do in a satin I can't do in POR15 since it only comes glossy. I might go and have a yak to a paint shop about something suitable... Quote Link to comment Share on other sites More sharing options...
danger Posted October 18, 2011 Share Posted October 18, 2011 i dont think POR15 would like that^ +1 POR15 falls off a well prepped surface. Loves a bit of surface rust etc for adhesion. Could always rough it back to matte with a scotchbrite after? or topcoat in satin enamel? Quote Link to comment Share on other sites More sharing options...
slacker.cam Posted October 18, 2011 Share Posted October 18, 2011 POR15 falls off a well prepped surface. Loves a bit of surface rust etc for adhesion. A sandblasted surface works very well too. Quote Link to comment Share on other sites More sharing options...
Spencer Posted October 18, 2011 Share Posted October 18, 2011 It will stick to bare steel if its been roughed up and hit with metal ready. They do a product called chassis black that can be applied while the por15 is drying, it comes in satin and is UV resistant, works well. They also have a primer that will etch into the POR15 with no sanding and enable you to appy any topcoat you like. I do agree with cam that a etch and 2pac top coat is also a good optiion If its bits that are visible in the engine bay the gold zinc plating Jase recomended looks awesome, gives a factory new look to some bits also Quote Link to comment Share on other sites More sharing options...
