Post engine fire clean up

[PbFut]

As some of you know, I had a pretty good engine fire 3 weeks ago. Hagerty has been decent to deal with on parts and allowing for self repair. I have the front clip off, engine out and 95% of firewall items removed. I was messing with various cleaning methods but not coming up with anything that does not require a great deal of rubbing with blue scotch-brite. The soot from burnt plastic is really bad. Has anyone with fire damage found a solution? Paint on the body panels escaped heat damage as far as I can tell but the soot will not release. I am no using sctch-brite on exterior. Polishing compound is working as that seem to be the ticket. But areas under removed panels and firewall is really bad. Tunnel and distributor area go too hot. Will need wire brush strip and prime. I have not removed interior as yet. So all that to ask for tricks in washing off this soot?

After you remove everything off the firewall, then use various diameter "roll lock" fiber discs on a die grinder or hand drill.

Yes for removing burnt paint, but what about areas not needing repaint? The fiber disc will put too deep of marks.

The soot is likely chemically bonded to the paint via heat. I know you don't want to hear my solution. Sorry to see what a mess the fire made of your truck.

Will wet sanding work?

All Exterior paint except hood is good. I experimented with polish used when I painted. Unless I find some heat damage, not expecting to, a good wipe down with paint prep and polish with compound will get it gack to 100. Firewall will need full strip to metal. Right fender on inside is heat discolored. I think I can strip to the hood channel seam and be good. Liners need strip and repaint. Cleaning just puts a step in that is not needed since I'll strip anyway. No getting around that the firewall is toast.

I wondered about that bond to unprepped paint, glad it's not fused on there. We used to remove fresh graffiti from heavy equipment with Brakleen and a rag, but that crap wasn't applied hot

If you have a Dollar Store (cheap) nearby, maybe try some oven cleaner along with Ajax or Comet with the heavy duty green scrubbing pads.

For the firewall I was thinking using the roll lock discs. But yes if you have undamaged paint areas the roll locks would be too course.

Maybe try this?

70Stovebolt, that looks like a good thing to try. OP might also try a Mr Clean Magic Eraser/Melamine sponge. They are essentially a very fine sanding sponge.

Try soaking it in wd 40?

[daddymoo2]

How about a pressure washing it and soap solution. Good luck.

I had not thought about those eraser sponges. Thanks for tip.

I've been following your thread and I find I find it quite amusing.. I feel really bad bringing you bad news.. I have some experience with fire damaged vehicles.. That black stuff is the remains of hot black smoke and burning particles.. The heat has bonded that stuff to the paint and it cannot be "washed off".. You will NOT be successful trying to "rescue" or save the paint, it is forever damaged.. Grind, sand, or otherwise remove the paint down to bare metal.. Treat the underlying metal and then apply any necessary fillers, primers, etc., and then apply color matched paint.. Feather it in with the surrounding undamaged area.

LOL. I hope it was just a poor word choice. Rusty is correct, sort of. The black soot does come off if the heat in that area was not too hot. It goes from oily and easy to remove with soap and wash cloth to elevated abrasive needed, to burnt paint. The outside of cowl cover got too hot. Repaint required. Outside of fenders looks good so far. I was hoping to wire wheel inside fenders up to the hood channel but the channel is not acceptable. I will try to meet at the top corner but I am not confident. That means bringing the color out around to outside of fender and stop at trim. Bummer as the outside paint realy turned out well for driveway spray. I messed with AC cover yesterday. SOS on the really bad stuff. The smaller cover is really toasted. There is plenty room inside to try and reinforce with resin and some mat. Then experiment with the gelcoat. Why I am obsessed with the ac cover with all the other stuff looking at me I don't know. I just roll with what ever bugs me the most at this point. I don't really know if the cover is salvageable so I obsess until i figure it out. Then easier to move to next part. Then I don't lay awake all night thinking about different procedures.

Sorry but on that truck I am not understanding why you just don't just do it right and sand it down the same as if you were restoring it from scratch, and paint the whole firewall and stand back and tell yourself nice job and put it back together. With trying to cut corners you are never going to be happy with the results in the long run. In truth you will probably get it done faster by sanding it down and repainting the whole thing rather than dink around trying to save part of the paint.
