Before I start cutting into the longs and hell hole I was thinking about sand blasting the whole area first to see what I have and then prime it before making the repairs. (eventually I am going to strip the whole tub. just doing it in sections) I already bought a blaster from eastwood. Now I need to get setup for painting so I can prime it immediately after stripping it. I have made a list of the main things I need to buy. I think I got most of it figured out but have questions on the primer and a good paint gun. I have never sprayed paint so any advice is welcome or if there is something i need to add to my list, let me know.
Here is a list of what I think I will need paint gun etching primer fresh air respirator hood throw away coveralls gloves metal prep I am sure I will need stuff to mix the paint with. The paint shop guys will help with that. I am also going to build a chamber to limit the mess from the blasting and over spray in my garage. I went to the local paint shop and they sell three brands of etching primer, nason, ppg and dupont. They are in order of price. Nason appears to be a low priced dupont brand. It's about half the price. Can I use the cheap stuff or should I stick with the ppg or dupont. Obviously I want to save money but I don't have a problem buying the right stuff if it is worth it and will work better. Actual suggestion items numbers would be welcome. I was also looking at paint guns. They had a nice 2 gun set from DeVilbiss, one for priming, one for painting, i think it was around $200. They had other guns that were half the price or lower. I think i have read on here that the DeVilbiss guns are the best. (or at least in somebody's opinion they were). Is it worth the extra money or will I get the same results with the cheap gun? thanks I know everybody likes post with pictures so here is one. ![]() |

For the most part yes. My problem is
a: there is nothing wrong with putting etch over the blasted surface. b: the reason I don;t use Eoxy is that it needs a rough surface to bond to and in the end it is simply a mechanical bond whereas the etch is a chemical bond. c: if you sand through the edge of eoxy, you can see it lifting at the break. I have actually broken through when sanding it and taken a blow chuck and blown ight on the edge and watched it start to lift on off. d: On the other hand , a good etch primer will breack through and have a nice featherd edge that won't lift. I use epoxy on things like suspension, or a car that is NOT getting a complete strip job as the bond between the old paint that I have sanded with 80 grit I then follow it up immediately with a spray poly so I get a chemical bond between the two of them, and the poly gets all of the sanding. |
