Abarth Posted October 15, 2021 Share Posted October 15, 2021 What’s good for painting the underside of wheel arches? I’m doing some panel work so I’ve stripped it right back to bare steel under there. Is it just Primer, paint and use some generic underbody paint, a few I’ve seen are rubberised or bitumen based?

WhangareiKE70 Posted October 18, 2021 Share Posted October 18, 2021 If buying Raptor and you don't get some sort of hectic discount at Repco, I would recommend sourcing it elsewhere (Car Colours in North Shore if Auckland based, or Union Hardware in Wellington, they sell on TM and regularly do special deals). I did a price check recently as I can get it from Repco locally, 4L tintable is $429.90 at Union Hardware, $599 at Repco. Fairly significant difference, worth getting it shipped. 2 Quote Link to comment Share on other sites More sharing options...
Evan Posted October 18, 2021 Share Posted October 18, 2021 Anyone know of a solvent that strips epoxy primer off/out of a gun? I got a bit lazy on my last couple of clean outs and have a bit caked in/on the thing. have tried Acetone/MEK/generic gunwash which got the thinner stuff off but not the thicker areas.

Yeah it’s expensive right, I was just going to use the aerosol version which is still like $99 bucks. Looks like only Repco supply that version.

Did you leave it soaking overnight in MEK? That will eat most things otherwise have had to send a expensive gun to get acid dipped cause full of hard set 2k Quote Link to comment Share on other sites More sharing options...

Be worth checking around, as Union Hardware have it listed on Trademe, and I know Whangarei Paint Centre have it on the shelf, so should be available elsewhere for you. As long as they are a Upol supplier they should have it/be able to get it. 1 Quote Link to comment Share on other sites More sharing options...

Spencer Posted October 27, 2021 Share Posted October 27, 2021 Hey boss, so yeah brunox or any single stage rust primer things go in the bin. Anything you paint on rust goes in the bin, in all the messing around I have done (painting panel steel and leaving it outside) any rust converter/primers are junk (they rust underneath all the time) Rust converting with acid or removing rust with abrasion then epoxy primer is the better solution every time, pretty much nothing has adhesion like epoxy primer. It is not really weather stable over the long term which is its downside, it is meant to be top coated and works super well with 2k urethane on top which is flexible and withstands the weather much better. That primer has no data sheets on that website? I am going to assume that 2K primer is urethane primer which is not for going straight on metal, it is generally the best shit for block sanding as it sands a little nicer and will usually have a mixing option to go on thick for blocking. A system many will use is epoxy on the metal, urethane primer high build for blocking then top coat. The paint stripper will probably not remove the seam sealer, it usually has to be scraped out. Had many issues with single stage primers & paints (and shit like POR15) reacting or not sticking to seam sealers so you want to test this out. Seam sealer should be urethane, generally they work best over the epoxy primer (which generally doesn't react with much shit) then bang the 2k urethane colour over the top but best to test your products out first before going crazy. for inside panels its tough. The best method IMO for rust patches is clean it all up and epoxy primer inside the repair and on the patch itself. Leave it to dry 24-48h and then clean up the weld areas and weld it in. Epoxy will hold out to welding a million times better than weld through primer but you have to have to wait for it to cure. since its already closed up just wax it. Get some 2k epoxy primer, its pretty safe to spray compared to Urethane 2K no isocyanates. I think I have said all this like 10 times 2 4 Quote Link to comment Share on other sites More sharing options...
Spencer Posted October 27, 2021 Share Posted October 27, 2021 I don't think there is much difference in brands TBH. I have not painted a car in like 7 years due to house buying and all that shit. But I used protec epotec 408 because it was cheap, been through shit loads of it like 5 cars worth. Think PPG bought protec so the line up has changed, someone else will have more up to date info https://www.kustompaints.com.au/product/ppg-408-epotec-epoxy-primer-n14-white-5l-kit/ Um looking at that repair if I was being a cunt/critical I would say some of those welds looks like they were not very hot and have not penetrated well anyway? with a mig I would basically only use spots/tacks an inch apart but pretty hot so you get good penetration through to the back and the weld goes down pretty flat. Then clean them up and do the next round of spots, its slow as hell but less bendy bendy and things stick together pretty well and you can grind them flat knowing its actually welded through not just shit on top. Not sure if I would bother cutting it out at this stage, its up to you. Like I am sure other cavities have surface rust and shit so chasing perfection can be pointless when just getting it good enough and then doing it again in 10 years will do 1 Quote Link to comment Share on other sites More sharing options...

Spencer Posted October 28, 2021 Share Posted October 28, 2021 You can brush the epoxy in there once you clean it up if you need. Then top coat it black or whatever. Quote Link to comment Share on other sites More sharing options...
