Thread: Jams, underhood, etc. on color change

Tweet

Do you clear coat the jams and underhood during a color change? Seems like a pain, so I don't know if is is necessary or normally done (especially under the hood for the firewall).

Thanks,

Scott

With basecoat / clearcoat panit, the clear is where the shine comes from. I doubt the basecoat would last long without clear over it. Once you get the jams and all cleaned up enough to paint, the clearcoat doesn't take long to put on....

Daves right , The BC/CC needs the clear for the shine , and Protection !
Dont skimp to doing a job right .
Find out if the color you are using can be mixed in a single stage as it doesnt require clear.
Make sure you clean jambs real well with soap and water first , then wipe real good with wax and grease romover , and when you sand the jambs you sand them good , because anywhere you dont get sanded will peal in time and , makes for a crappy looking job when it all starts popping off.

Best way to do a color change is to blow the vehicle apart.

Big point to keep in mind is the old sayin bout the harder it is to sand an prep the more important it is to do it right..as THAT is where the paint will lift an peel, it goes double for jambs interior an underhood areas! as it is obviously a pita to do, plus the grease, mildew an funk accumalted after years an miles, an sometimes its simply looked as not as important as the outside, but these areas area what helps show the level of work an detai lput into the job, ive had to do many over the yrs that i didnt have time or help in doin jambs an underhood, and even with an awesome paint job, these areas ruin the whole "finished" look of the car if not done right!
on a side note, dependin on the quality of paint your goin for, some bc/cc systmes( standox for one) wil allow mixin a hardener in the basecoat for a semiglos look, if yr not goin for a full custom glosy look,

Use scotchbrites to sand the jams. It's a lot easier, and gets into the corners better. Most production shops shoot the jams in single stage, mask, and do the outside in BC/CC.

Thanks for all the info. I'll check on the single stage for the firewall and underhood, from my supplier.

But I guess I have a lot of "under the hood" bits to move now. Blowing apart them main body is no big deal (a few bolts). The vehicle is a Hummer (a real one) and they are made too be dismantled in the field. The engine compartment is a little work though as it has air compressors for the tires, and all kinds of do-dads mounted on or in front of the firewall (plus padding for noise) Easy to work on the bits, tough to totally remove.

My guess is you would use a little air-brush in these places.

Thanks,

A touch up gun is a smaller overall gun in size, works great on tight spots that a big gun is too big to get in to.

I agree with dave. The airbrush won't work well for this. I'd also use a touch up gun.
