do i really need plastic primer

[novashed]

painting of the shell is underway, do i really need to use plastic primer for the bumpers? would i just be risking it not using it? painting in celly BTW.

[lee may]

Yes you do.

It will flake off if you dont

[D4NNY]

celly on bumpers

mate trust me if ya using celly u def want an adesion promoter first then plastic primer!!

u using aerosoles or through a gun??

if aerosoles try to use an acrylic like 2k as will flex alot more

[novashed]

using proper setup gun etc.

just wanted opinions, glad u've replied

acrylic isnt a 2K paint, think i know what you mean though rattle can plastic primer, would rather use with the gun, much better coverage

[novashed]

just a though an etch primer would do a similar job? can be bought in rattle cans. the bumpers themselves have had extensive smoothing, so half filler and half plastic interms of the surfaCE AREA

[BigbaRd]

upol plastic primer is only 12-95 per litre, I quite like upol stuff - good make.

is it normal filler you used? should have used the grinder on it really for the filler to grip if it's normal filler (the flexible stuff be alright though if you used that)

[novashed]

no worries on the grip thing, drilled lots of tiny and larger holes, done few bumpers over the years, with same technique all been fine.

using tetrosyl stuff atmo

the upol stuff is it acrylic based?, be ok with celly topcoat?

[ScottsportUK]

we just scotch bumpers and apply u-pol adhesion promoter, never had any come backs yet.

[MuppetMule]

I have a litre of Max Meyer plastic primer, good stuff, 1k I believe, cost £35 and never used it. Will sell it for £15 INC postage if your interested.

[BigbaRd]

i'm not sure actually, ill have a look on it tomorrow see if it's acrylic based or not. it'll say on their will it?

[novashed]

would of thought so



muppet, this 1K, is it compatable with celly then?

[D4NNY]

we supply all the brands you have mentioned above and all are good makes,

yes you can use the 1k with the celly mate,

2pack acrylic topcoat i was refering to in my first thread mate, (Duralit) as you can add flextane to it alowing alot more movement, you can get plastic primers and adesion promoters all in rattle cans upol do them for aroun 8.50 a can, have u not considerd using a polyester basecoat and then 1k laquer?? as is alot nicer to spray than celly??

jus a thought mate

[D4NNY]

all our paint is maxmeyer ::: Maxicar = polyester basecoat,, Duralit = 2pack,, Bilux = Cellulose

[novashed]

done a couple of bits in the celly, and the results are top class, im well chuffed, ill post a pic of the cam cover ive done to test the colour.

another Q if anyone can, the doors i have are from my old car, perfectly smmoth but done in basecost then clear coat, 2K i believe, is it possible to just scotchpoad them down and top coat withe solid celly topcoat im using, just a thought as they are dent free and proffessionally done in the first place, would save me alot of time flatting them down to primer again.

[BigbaRd]

I couldn't find anything on the plastic primer so I just took a pic lol actually I forgot what I was looking for



the back if you can make any of it out:

heres A pic of my efforts with the cam cover



well chuffed wthe gloss, the pic doesnt do it justice, as still getting to grips with my new digicam got today for me b'day.

[D4NNY]

mate looks top job, especially for celly

about the basecoat you should be fine to scotch it down to give the celly some grip,

remember as is lacquer it will rub away and look all white.

[novashed]

cheers for that bud, wot i might do is test the door shut side first to see what it goes on like before the outer skin where quality has got to be paramount

[D4NNY]

yeh sounds good plan mate keep posted on how it comes up!!

[novashed]

will do, hoping to put together a progrees thread just gotta get round to it, will keep taking pics as i spray each part of the car though
