Undercoat weel whells

[autumn ash]

Hey, so im thinking about just hitting the rusty spots with por and then top coating everything with rustoleum truck bed liner. But there is still under coating in the wheel well (in pic) , my question is do i heat it up and scrape it off or just paint over it? (I would obviously sand it a bit and make sure all the losse or peeling parts are off.)

I'm not sure I'd go the bedliner. That'd be a real beeotch to clean up if you ever needed to remove it. I think I would use something like Restoleum oil based industrial direct to metal paint. It's pretty dang tough.

I use a rubber type base made for inside fenders on trailers and RVs. It lowers the noise level substantially and isn't too hard to scrape off or touch up. It's available in rattle cans or spray on with a big (1.4 mm) tip on your gun.

Scrape the under coat off. Don't use bed liner or future repairs if needed will be difficult. No body shop will repair the car.

That's one hell of a good point.

I think a rubberized undercoating would be best. I've never liked the aerosol can products from the local parts stores. SEM makes a great undercoating which is sprayed with a Shutz gun (about $20) and is much closer to OEM than the spay can stuff. I have used Raptor liner and it looks good but it cures very hard and would not cut down on noise from rocks as well as rubber coatings. As for repair with a bed liner, you simply would use a knotted wire wheel on a grinder or die grinder and remove it where the repair is to take place. I wouldn't be afraid of it myself and if it is being fixed by a shop, well that's what insurance is for, i.e., to put you back in the position you were in before the accident.

Rubberized undercoat (SEM) makes a good product.

Might go with that then.

This matches the original existing sound deadener on my '66 (10,000 mile car) the closest to anything I've found...

If you aren't going rotisserie build and blasting everything, this is a very viable option that looks clean and will protect the underneath of the car.

Alright thank you.
