Yea I know that sounded pretty pathetic didn't it. LOL! Truth is I have bad legs and feet so sometimes i push too hard.

Ground out the old bondo and pulled out the dent a little with my stud puller, hit it with a little acid etch then started applying new mud yesterday, got it roughed in. Naturally I forgot to snap a pic again. 🙄

Re: Rat repair.

Late start after work, realized I still had to go get the EX-3 extractor, more kroil and heat, 3 times no budging it, drilled it up a bit more, repeat, nope! Drill up to 1/4", more heat and oil, nope! Brought out the chisel, center punch and a sharpened drill bit and started chipping away at it, tried to start a tap got a little ways then because the hole was off a little on the back side it dislodged it a little so I tapped it out from the back side then ran the tap through it, figure I got about 75% of the original thread remaining. That only took me 2.5 hours including the trip to the hardware store.

Re: Rat repair.

I suspect most of us following have "been there, done that" and had those days. Keep up the good work.

Re: Rat repair.

Well this is where I'm at, ran out of high build and self etching primer but I think the outside of the fender is almost done. Per the area in front and below the marker light, I seem to have added considerably more mud than what was on it, but it just seemed like it needed it.

Re: Rat repair.

A little advice please, I should have probably sealed the fender in primer right after I sanded the paint off the fender because I got sidetracked and progress stopped, now my finger oils have created some surface rust, what's the best way to remove it? Don't want to over sand, should I wipe it with something that will eat the surface rust like the Gem rust killer I have then a light skuff with a da?

You can make up some prep solvent by mixing equal parts isopropyl alcohol, acetone and water. Shake well, pour a small amount in a dish, then dip a grey or maroon scuff pad into it and scrub the affected area. Wipe it with a clean cloth or paper towel to remove the residue. Let the area dry thoroughly... at least 45 minutes in warm sunshine. Self etch or epoxy primer will bite right thru any tiny amount of surface rust that remains.

GEM Rust Killer is a "converter" (phosphoric acid + iron oxide = iron phosphate) which is a great surface prep for powder coating. If you plan to epoxy primer over it, you may want to first treat it with a mildly acidic solution like vinegar and water or 20% HCl. At least that's what some epoxy manufacturers recommend. Others say just squirt the epoxy right over the iron phosphate. At a minimum, if you treat it with the GEM, I'd scrub it good with the prep solvent I described above before applying any primer. And as I mentioned, it needs plenty of time to dry thoroughly.

Re: Rat repair.

Ok , nice break in the heatwave/forest fire smoke wave from Canada that we have been dealing with for about 3 weeks, figured I best get a little more done, sanded the front bondo coat down a little as I thought it was a bit excessive, made the 3 parts Water/Acetone/Denatured Alcohol and scrubbed off the surface rust, grabbed my DA sander and gave the exposed metal a quick skuff, then a light hand skuff on the bondo areas, gave it a good wipe down and shot 2 coats of K2 on the outside. Will let it cure for a bit before I do the inside. Yes the pic is upside down, no time to download to my computer and edit it. 😁

Re: Rat repair.

So I do seem to approach things a little backwards sometimes, I probably should have prepped and primed the inside first, it was just a little messy! The driver fender wasn't near as bad as this one so I didn't prep or prime the inner part at all but this side needs all the primer and paint it can get. Spent today prepping, masking, touch up sanding and wiping the inside with alcohol, then Mineral spirits, then hung it up, will give it a final wipe down with wax and grease remover tomorrow before I prime it. ( and again the pic needs to be rotated, it's hanging upside down ).

Re: Rat repair.

Got the inside primered about an hour ago, maybe 2? Was sitting here thinking how nice it would be if I could just mix up some color and top coat it without any prep within a certain timeframe, is this a pipe dream?

This is PPG DP50lf grey primer and DP402lf catalyst.

Top coat is DCC single stage with DT reducer and DCX61 hardener, ratio 4:2:1

This is the pdf for the top coat. http://www.myrv10.com/N104CD/paint/p-168.pdf
