I wouldn’t say more concerning in terms of it being more dangerous, just more expensive to fix. The reinforcement is $400 from Toyota and it isn’t a slide over frame section. The old reinforcement has to be carefully removed and the new one has to be put in, which is usually more costly. If you have it repaired I would recommend fluid filming the insides of the frame and the outsides

Any thought or prior use of these types of fixes?

I can’t imagine they would have much impact resistance if you get into a collision

@fourwd1

I appreciate the insights. I want to have this fixed right. The guy I took it to showed me some examples in his shop of their work. It looked really good. He said they charge $3-4k, however thats because they take off a ton of stuff to do it right. The new coating looked like a thin Rhino Liner over the whole frame.

I guess my issue is a) I would like these two holes fixed before the winter so they don't get worse (and peace of mind), and b) the cost to do the whole coating is pretty expensive and not sure I can afford that yet.

@04rnr

Thanks for all the insights and help. The rear bumper area definitely has some holes in it. I’m not sure under the fuel tank as I haven’t dropped this area.

Does anyone have pictures of the areas I should look for with the fuel tank dropped? It would be good to see what we’re talking about.

In the meantime I had someone fix the front hole on the passenger side near the control arm. The guy who fixed it said the drivers side was only the size of a quarter and wasn’t overly concerning to him.

He also welded in new bump stop brackets in the rear. Both he basically rescued off. He plugged the rear holes with a patch job for now and por-15 the entire frame. He also put thicker coating around the front rails where the repair was to protect it.

I never saw the weld work on the front but I saw the rear brackets. Could of probably done a better job wire wheeling as the por-15 looks like it was put over some flaking areas. We did not drop the tank of fox the gas strap.

We left it at next summer we’ll take the rear bumper off and do the tank. He thought the skid plate and other strap is fine to hold the tank for now.

I paid $900 for the front weld, rear brackets weld, Por-15 and undercoating. He said a couple of the rear brake lines were getting prett corroded.
