What is the acid stuff called in POR15..i saw it here, did a search and cant find it....somone..i think George N said he uses it all the time, i just cant remeber..
I don't think there is phospho on por15. Por15 is a moisture cured urethane Acid based paints like etch primers cannot be applied over ospho based surface conditioners. Por15 can, and por15 metal prep is ospho based
Phosphoric acid is in HD and it works great...no need spend extra money on POR15 when acid works just as well and is cheaper.
Is this it? http://www.homedepot.com/h_d1/N-5yc...splay?langId=-1&storeId=10051&catalogId=10053 Thanks. I've never used it before, and my trunk floor has quite a bit of surface rust showing. I was going to wire wheel it, and then go from there. Using the info from the other thread, I think i'm set. Wire wheel. Vacuum and wipe down with acetone or mineral spirits. Acid. Clean up residue from acid. Undercoating spray. Splatter paint. Carpet. Wheel cover from caddy. :TU:
Without knowing the concentrations of the phosphoric acid in the different containers there is no basis for price comparison. For all you know the more expensive product has twenty times the concentration of the cheap stuff making the value much better. Read the fine print so you can make an educated decision regarding value. Devon
Hey cool I work for the company that makes the Klean Strip product that Home Depot sells.I could probably find out the percentage of phosphoric acid in it if anyone is really interested
Being that I am 2 days away from stripping my car down to bare metal, i'll have to swing by home depot and see for myself. :TU:
***** I don't think there is phospho on por15. Por15 is a moisture cured urethane Acid based paints like etch primers cannot be applied over ospho based surface conditioners. Por15 can, and por15 metal prep is ospho based ***** --> I treat all my metal with Ospho but have no idea if all my rattle cans (doing unerhood stuff) can be applied over it. What is the rule of thumb ? Anything that I should know ? I though all paint could go over Ospho
AAAAAAAAAAAAAArg !!! OK I am a rookie ! I'm redoing my dynamo. I took both end's off and I: Sanded Wire brushed Ospho'd Cleaned with thinner Primered (can paint) Painted (can paint) I was not happy with the coverage so i put several thin layers yesterday. I looked up close and saw little bubble marks (photo) so today i decided to put another layer (but thicker)... and I still have the bubbles (see photo) !! What am I doing wrong ? Is it too thick ? Does it not like the primer ? Did I not wait long enough for primer to dry (waited 1-2 hr , I usually wait overnight) Not clean enough ? Did not rattle the can enough ? I thought I did everything properly.... Maybe my paint (bought in auto shop) is too cheap ? In photo you will see some bad spots - I tried to redo the pinholes with a paint brush !!! I screwed it up.. Waiting for it to dry and sand it all down to repaint :-(
I believe the active ingredient is tannic acid. It converts rust (iron oxide) to iron tannate (the rock form of iron). It also has a protective polymer as a sealant.
Whatever it is, you're doing wrong; I must be doing the same. I repainted the generator (dynamo). And, it looks like $||*- !
