Helping a friend with his car we cut out any rust and welded in new metal, but where the new metal is it's bare is there an under spay/similar that comes in a can ?. We'd like to coat it before it gets onto the street vs after. The roads north of Toronto are horrid !


thx

 

First spray on a good primer.

Then spray on an epoxy chassis paint.

Then spray on an undercoat. Don't cheap out on undercoat. Buy the 3M stuff.

Yes it works. Roads in Chicago/burbs are bad too. I'm the world's #1 rust hater. I always epoxy and undercoat entire chassis' for any of my DD's. I do it in summer. I put the car on stands or the lift. I wash the chassis with my pressure washer and watch a garage movie (usually its a pr0nz) whilst waiting for the car to dry. Then I coat everything. Control arms. Fender lips. Chassis. I. Dont. F#&k. Around.

 

Amazon has all that stuff for fairly cheap if you can't find it at a parts store, BTW.

 

Alright i'll look for that tomorrow (3M brand).

 

Can be had in most big box hardware stores.

 

Ok thanks I'll know what I'm looking for now.

 

That rubberized undercoating doesn't stick too well, so please clean that thing thoroughly with SuperClean and hose/pressure before even doing anything.

Dilute SuperClean 50% with water or it can remove paint.

 

Definetly prime it like a professionnal. Search for the 50$ paintjob thread.
