painting bruiser chasis

[anthguteirrez]

:Tamiya1: i just got a tamiya bruiser and i want to strip the already falling off painting on the chasis can anyone help me out? also with what can i repaint it with? thanks yall

[Suprachrgd82]

Supra found that getting paint to stick to the galvanized chassis is difficult. In leiu of this, Supra used "self etching" aerosol primer, and Duplicolor engine enamel.

Self etching primer is expensive (upwards of $12 per can), but bonds quite well to the chassis.

Duplicolor engine enamel leaves a super glossy finish that is chemical resistent and very hard. It seems to be the next best thing to powder coat.

cool thanks, i think maybe polishing would be easier but color would make it different.
hey do you know how to strip and repair the body as well?
ive heard that brake fluid and or oven cleaner but iono, and i ended up cracking the license holder so :( let me know thanks

[Suprachrgd82]

Supra stripped a body using brake fluid (not cleaner). It required several days of soaking and scrubbing with a green scubbing pad. Others may have experience with the oven cleaner.

Supra recommends painting the chassis. Polishing will leave abre metal, which is prone to oxidation. Paint will seal it, and keep it looking good.

The body can be repaired with styrene sheet reinforcements and model glue. If filling is needed, Squadron Green Putty works well on small holes. Glueing in sheet styrene is better for larger holes.

how should you polish or prep the chasis and diffs for primer? i was useing sos pads and it was shining them up is that good ? anyone let me know :yourock:

[Suprachrgd82]

Good surface prep will remove all oils and grime. Supra uses lacquer thinner for metal parts, and rubbing alcohol for plastic parts. be sure not touch the parts once you have wiped them down or it will leave trace oils from your skin.

supra thanks your great help to bad not everyone is like this hey dont mean to bug but can you help with electronics?

i already stripped the chassis with jasco stripper sweet stuff:Tamiya1:

.... can you help with electronics?



Supra is mostly a plug & play kinda guy, but may be of some assistance.

Supra, Thanks for the tip on the self etching primer. Going to try it on the axles and tranny on my Blazer. Found some at an Advance Auto store for just over $5 per can. Not thrilled with the color as I will have to use another color to cover it before final paint. But if it works it will save me lots of money as I was thinking of having these parts powder coated.:first:

supra i have the original esc but i cant get it to work properly (accelerates quickly no slow crawling) and maybe its th 7.2v 1800mah from my e-z start i just had around(the resistors started smoking).....so i was thinging about upgrading maybe to a novak? something advance any recommendations?

The best ESC you could get it should have different acceleration curves, you can select then usually pushing a small button.

yeah i was looking at different esc like those, let me ask when you have an esc like those do you still need throttle linkage/servo?:help:

[tc1cat]

No linkages or seperate sevos for speed. That is one of the advantages of the ESC. Plus a much greater control of your speed.

appreciate it!! do you have a recomendation on any esc they do get very expensive and i want to get one that works but not expensive also they rate for different turn motors my bruiser has the 750 so im not sure what is suitable let me know thanks:yourock:

[tc1cat]

Can't really help you with the ESC for a 750 motor. Maybe one of the many builders can help you. I only have experience with the 540 and 550 motors and ESCs. I had a Bruiser many years ago which I sold like an idiot and just used the mech. speed control. Redoing a Blazer now but it has a 540 in it.

[anthguteirrez]

thanks hope fully some one can!:focus: i know this tread is for paint but if anyone out there knows about setting up an esc let me know thanks!!!!

tc1 where did you get the self etching primer? let me know how it works also!

i took off most of the paint from the chassis with a stripper it seamed that some areas the paint left a stain i tried more stripper and steel wool but no luck anyone?

[anthguteirrez]

supra!!! hey when you soaked the body in brake fluid(alot of people seem do be doing it) what kind of pad or rag or sandpaper did you use to clean the body and get the paint off? thanks

[Suprachrgd82]

Supra used a green plastic scouring pad and an old toothbrush.

http://www.3m.com/us/home_leisure/scotchbrite/products/scrubbing_scouring.html

Supra would not use anything abrasive to plastic for fear of rubbing off the detailed body parts.

It took 3 days and a lot of scrubbing, but it was worth the effort to come out with a perfectly stripped body.

[anthguteirrez]

awesome i think ima start on the front grill first to test this out i appreciate all your help!!! thanks
hey do you know what works best to glue back pieces to the body( the grill holder mount broke)?

[Suprachrgd82]

Supra was recently turned on to this cement by a pro model builder at his LHS.

Supra is anxious to see pics! Glad everything worked out well.

:frusty:darn maybe i spoke to soon i was putting together the chassis and the paint started to come off when i tightened the screws :( back to the drawing board (i didnt use thinner to clean parts that may have been it i just washed them :( i have more paint ima try thinner)

[Suprachrgd82]

Supra's did the same if he really mashed down on the screws. Supra then baked it in the oven at 250 to cure the paint, which helped a little.

[anthguteirrez]

i guess theres no good way around this it was looking pretty sweet ima leave it like it is then strip it again later :( thanks thought maybe some day we will find something great to work ha!:Tamiya1:
